2020 Chrysler Voyager Key Replacement
Short answer: The 2020 Chrysler Voyager belongs to the Voyager RU (Pacifica-based) and uses a smart proximity key with push-button start. Its immobilizer chip: Hitag AES (ID 4A). We can usually add spare keys on site; some situations, such as all keys lost on certain trims, need extra steps or a dealer-supplied part. Julian's Locksmith cuts and programs Voyager keys on site; call (951) 903-3193 with your VIN for a quote.

Losing the only key to a 2020 Chrysler Voyager usually happens at the worst moment: a parking lot after work, a trailhead, a driveway with the kids already buckled in. You don't need a tow truck or a dealership appointment to fix it. Julian's Locksmith drives a fully equipped service van to you in Southern California, confirms you own the vehicle, then cuts a new blade and programs the chip or fob right where the car is parked. Before we roll, we'll tell you over the phone what your Voyager needs, whether that's a simple transponder key or a proximity fob, and what the job will involve. You get a quote before any cutting starts, and the decision stays yours.

The modern Voyager uses the Pacifica's proximity smart key, FCC ID M3N-97395900, with push-button start. Fobs range from three to seven buttons depending on power sliding doors, power liftgate and remote start, and supplier listings include KeySense-capable versions as well. An emergency blade is stored inside each fob for the driver's door, and the battery is a single CR2032. Supplier catalogs carry the Voyager through 2024, so we confirm later years by part number.
What's specific to the 2020 Voyager
2020 was the first model year of the Voyager RU (Pacifica-based). Early-production cars sometimes use different part numbers than later ones, so for a 2020 Chrysler Voyager we confirm the exact key from the VIN or the old key's FCC ID before cutting anything. It also marks a change from the previous generation: the 2003 Voyager used a transponder (chip) key and a key with a separate remote fob, while the 2020 uses a smart proximity key with push-button start. Keys from the older car will not work in this one.
A 2020 Chrysler Voyager is about 6 years old now. Original fob batteries are near the end of their life at this age, so weak range or a "key not detected" message is often a battery before it is a failed fob. Cars this age are often on their second owner, which is when a single remaining key and a request for a spare tend to show up. Smart-key cars like the 2020 Voyager can be targeted with relay attacks that extend the fob's signal from inside your home, so keep fobs away from exterior walls or in a signal-blocking pouch, and have any missing fob erased from the car.
Key options for the 2020 Chrysler Voyager
- Smart proximity key (push-to-start). Proximity keys bring a security trade-off worth understanding. Because the fob is always listening, thieves with relay equipment can stretch its signal from inside your house to the car in the driveway. Keeping the fob away from exterior walls, or in a signal-blocking pouch, closes that gap, and some fobs offer a sleep mode described in the owner's manual. If a smart key for your 2020 Chrysler Voyager is lost or stolen, programming a replacement is the moment to delete the missing fob from the car's memory. And be wary of used fobs from online sellers: a lot of them are locked to the vehicle they came from and can't be reprogrammed to yours.
How the Chrysler immobilizer works on the Voyager
- The Voyager was sold to fleets only for 2022–2024 and returned to retail sale for 2025.
- Supplier listings show the same NXP Hitag AES fob family for the Voyager and Pacifica, but each fob must be programmed to its own van.
Programming a 2020 Voyager key
Programming follows the Pacifica process: a current tool, access through the secure gateway module, and the vehicle PIN, all over the OBD-II port. Adding a spare while one fob works is straightforward on most vans. If every fob is lost, some vans can still be done over OBD-II, while others need the radio frequency hub handled directly or a dealer, so we check your VIN before scheduling.
Most Chrysler key work runs through the OBD-II port and a 4-digit security PIN tied to the vehicle. Current programmers can read that PIN from the immobilizer on many older models; on others it comes from the dealer by VIN, which requires proof of ownership. Many cars through about 2010 also have an owner-level key-learn routine, but it needs two working keys already in hand, so it is no help once you are down to one or none. A remote-head key can need the chip and the buttons learned in separate steps, so a key that starts the engine may still need its remote side set up. Most 2011 and newer remotes need a programming tool. On 2018 and newer vehicles, the secure gateway module adds a bypass cable or authenticated login to every job. Before we cut or program anything we verify your ID and ownership, and we quote the whole job, including key, cutting and programming, before starting.
Spare fobs are routine; all-keys-lost can require module work or a dealer on some vans.
Lost every key to your Voyager?
- Gather your documents and the VIN. Call with the year, make, model and VIN if you can read it through the windshield, plus where the car is parked. Those details let us confirm whether your Chrysler Voyager can be done on-site and bring the right key, so the first trip is the only trip.
- Get into the vehicle without damage. If the car is locked, we open it with non-destructive tools such as an inflatable wedge and a long-reach rod, or by picking the door lock. Some vehicles need a careful approach to avoid triggering the alarm, which can interfere with programming later.
- Originate a new key from the car. Originating a key means building it without a sample. The door lock usually reveals most of the cuts; any it doesn't are worked out by test-cutting and trying the ignition or a second lock. The finished blade should feel like a factory key, not a forced fit.
- Program the key to the immobilizer. Next, the new key is introduced to the car's security system. Many vehicles allow this through the OBD-II port with a PIN or security procedure. Some all-keys-lost cases require reading a module on the bench, and a few platforms only allow dealer programming, which we'll tell you up front.
- Erase missing keys and add a spare. Once the car starts, we remove the lost keys from memory wherever the system allows, so they can't start the engine if someone finds them. Making a second key during the same visit costs much less than a repeat all-keys-lost call down the road.
Why a spare key pays for itself
- Some vehicles make it hard to add a key once you're down to one. Certain immobilizer systems let an owner program an extra key on-board only when two working keys are present, so a second key preserves the easy options for later and avoids a full reset.
- A spare turns a future all-keys-lost emergency into a simple add-a-key job. With one working key in hand, programming is quicker, and the chip or fob can often be paired without decoding locks or reading modules, which keeps the cost of a lost key far lower.
- When you sell or trade in the vehicle, buyers and dealers expect two keys. A missing key can come up during an appraisal or a private-sale negotiation, so having both on hand keeps the conversation about the car, not about what it will cost the next owner to replace one.
Dealer or mobile locksmith?
Dealers have one clear advantage: direct access to the manufacturer's own systems. Some newer vehicles tie key programming to online authorization that only a dealer can use, and certain all-keys-lost situations on specific platforms still require it. A good locksmith knows where those lines are. Where we can do the job, we use professional programming equipment that talks to the same immobilizer and keyless systems through the OBD-II port, and in many cases the result is identical: a properly registered key that starts the car. Where we can't, we can often still help by opening the vehicle, cutting a mechanical blade from code, or helping you gather what the dealer will ask for so that visit goes smoothly. For your Chrysler Voyager, ask us directly and you'll get a plain answer.
Voyager key battery
A fob battery rarely dies all at once. The warning signs build: you have to get closer to the car before the doors respond, the dash shows a key battery or key-not-detected message, or the push-button start only works with the fob held near the button. Inland heat speeds that decline, especially for fobs left in a hot cabin or on the dashboard. Keep a spare CR2032 at home in a cool drawer, sealed in its original package, and buy from a busy store where stock turns over quickly. A cell that sat on a shelf for years may arrive already partly spent.
How the job works
- Identify the exact key your Voyager uses. We ask a few quick questions on the phone: the year, whether the car starts with a turn key or a button, how many keys you have left, and whether the remote still works the doors. Then we check the VIN against our programming references so the van arrives with the correct blank or fob, not a close guess.
- Verify ownership before any work. Before cutting or programming, we compare your government photo ID with the vehicle registration or title and check that the VIN on the paperwork matches the VIN on the dash. If the registration is locked inside, we open the car first, confirm the documents, and only then make the key.
- Get the key code or decode the lock. If you still have a working key, we can read its cuts directly and check them against the factory depths for the Chrysler keyway. A worn key gets corrected back to spec during this step, so the new key turns crisply instead of reproducing years of wear in a fresh piece of metal.
- Cut the blade on-site. Cutting happens right beside your car. For a smart key, that means the emergency blade hidden inside the fob; for a transponder or remote-head key, it's the main blade you'll use every day. We deburr the cuts and check the fit in each lock so nothing binds or sticks later on.
- Program the chip, remote or smart key. With the blade done, we connect to the OBD-II port and register the new key with the immobilizer. Depending on the Chrysler system, this may involve a security PIN, a timed waiting period, or on-board button sequences for the remote. On some vehicles we clone a working key's chip instead, when that's the more reliable path.
- Test everything and clear out old keys. Before we leave, every function gets checked: doors, trunk or liftgate, panic button, remote range, engine start, and the emergency blade in the driver's door. If keys are missing, we delete them from the car's memory where the system allows, so a lost key can no longer start the engine.
What affects the price of a Voyager key
- The type of key. Price follows complexity. The more the key does, the more it costs to replace: brass blade, then chip, then remote buttons, then full keyless entry and push-button start. If your Voyager came with different key styles by trim, the one your car actually uses is the one that sets the quote.
- Factory or aftermarket parts. Factory keys and fobs carry the manufacturer's part number and usually the highest parts cost. Quality aftermarket keys use compatible electronics at a lower price and work well on many vehicles. We tell you which options we trust for your car, and where an aftermarket version has known range or fit issues, we steer you to OEM.
- Blade style and cutting. Traditional edge-cut blades are quick to cut. High-security laser-cut blades, with a groove milled into the side, need a specialized machine and more care, and the blanks themselves cost more. If we have to decode a lock to find the cuts, that adds labor as well.
- Travel, timing and extra repairs. Sometimes a key problem is really a lock problem: an ignition that won't turn even with the right key, or a door cylinder that has been jammed for years. Fixing those is separate work. We point them out, explain the options, and quote the whole job up front so the bill holds no surprises.
Call (951) 903-3193 with your VIN and the keys you still have, and we'll quote the job before any work starts.
Tips from a mobile locksmith
- Southern California heat is hard on keys. Fob batteries drain faster, plastic housings turn brittle, and rubber button pads crack when a key spends summer afternoons on a dashboard or in a sunny cup holder. Carry the fob with you or keep it shaded, and replace batteries before summer rather than after they fail.
- Be careful with discount fobs from online marketplaces. A listing may match your remote's shape while using a different frequency, chip or FCC ID, and many used smart keys are locked to their original vehicle. If you already bought one, send us the listing or a photo before the visit so nobody pays for a programming attempt that can't work.
- Never hide a spare key or fob on the outside of the car. Magnetic boxes in wheel wells and under bumpers are the first places a thief checks, and with a proximity fob, a hidden key can let anyone open the doors and drive away. Keep the spare at home or with someone you trust.
- Every so often, use the mechanical blade in the driver's door lock. Cylinders that go years without a key can seize from dust and dried grease, and you won't find out until the day the fob dies and the blade is your only way in. A small shot of dry lubricant keeps the lock ready.
- Photograph the back of your fob and any key tag that came with the car. The FCC ID, part number and key code printed there make ordering a replacement faster and more accurate. Store the photos somewhere you can reach from any device, not only on the phone that might go missing along with the keys.
Proof of ownership
Before we cut or program a key for any vehicle, we verify that you have the right to it. Please have two things ready: the current registration or the title, and a government-issued photo ID with a matching name. We also check that the VIN on those documents matches the VIN plate on the dashboard. If the registration is locked inside the car, that's fine; we open the vehicle first, check the paperwork in the glove box, and only then make the key. If something doesn't line up, we stop and sort it out before any key is made.

Frequently asked questions
Can a locksmith make a key for a 2020 Chrysler Voyager?
We can usually add spare keys on site; some situations, such as all keys lost on certain trims, need extra steps or a dealer-supplied part. Spare fobs are routine; all-keys-lost can require module work or a dealer on some vans. The 2020 Voyager uses a smart proximity key with push-button start.
Why does my Voyager crank but not start with a newly cut key?
That pattern points to the immobilizer, not the engine. The blade is cut correctly, so the ignition turns, but the car doesn't recognize the chip and blocks fuel or spark. A flashing security light usually confirms it. The key either wasn't programmed, carries the wrong chip type, or is an unprogrammed copy from a hardware store. Programming a correct key to your 2020 Chrysler Voyager resolves it.
What do I need to show before you make a key for my Voyager?
A current registration or title and a government-issued photo ID in the same name. We match the VIN on the paperwork with the one on the dashboard before any cutting or programming. If you're not the registered owner, bring the owner's written authorization and a copy of their ID. If the documents are locked in the car, we'll open it first and check them there.
What happens to the key I lost? Can it still start my Chrysler?
When we program new keys, we can usually erase lost keys from the immobilizer, which stops them from starting the engine. On some systems the car only remembers the keys present during programming, so the lost one drops off automatically. Keep in mind that a lost key's metal blade can still open the doors, so if it went missing with something that shows your address, ask about rekeying the door locks.
Can you make a Voyager key from the VIN alone?
The VIN is a starting point, not a finished key. For many vehicles, the factory key code can be obtained from the VIN through manufacturer channels once ownership is verified, which lets us cut a blade that matches your locks. The chip or fob still has to be programmed at the vehicle, so we need access to the car itself. Where no code is available, we decode a lock instead.
How much does a replacement key for a 2020 Chrysler Voyager cost?
It depends on the key type, whether you choose a factory or aftermarket part, whether any working key is left, and how the Chrysler security system handles programming. A spare for a car with a working key costs less than an all-keys-lost job that needs lock decoding or module work. Call with the VIN and we'll give you a specific quote before we drive out, and nothing changes once we arrive unless you approve additional work.
Is the 2020 Chrysler Voyager push-to-start?
Yes. The 2020 Voyager uses push-button start with a smart proximity key, so a replacement has to be a programmed smart fob, not just a cut blade. The fob also hides a mechanical emergency blade for the doors.
What battery does a 2020 Chrysler Voyager key use?
Fobs for the 2020 Voyager use a CR2032 coin cell. Replace it when range drops or the car shows a key-battery warning. If the fob still fails with a fresh battery, the board, buttons or programming may be the problem, which we can test on site.
