2007 Chrysler Sebring Key Replacement

2007 Sebring key specs

The redesigned Sebring arrived as a 2007 sedan, with the convertible following for 2008. Both use a remote-head key on the Y159 keyway with a Philips ID46 chip, listed under FCC ID OHT692427AA, or OHT692713AA and OHT692714AA on some cars with remote start. Convertible keys can carry extra buttons for the power top, which can be lowered from the fob. A plain ID46 transponder key without buttons will also start the car and works well as a spare.

What's specific to the 2007 Sebring

2007 was the first model year of the Sebring JS (3rd generation). Early-production cars sometimes use different part numbers than later ones, so for a 2007 Chrysler Sebring 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 2006 Sebring used a transponder (chip) key and a key with a separate remote fob, while the 2007 uses a remote head key and a transponder (chip) key. Keys from the older car will not work in this one.

A 2007 Chrysler Sebring is about 19 years old. Original keys are often worn smooth, and some factory remotes for cars this age are discontinued, so we may suggest a quality aftermarket remote or a separate fob. Because older immobilizers are simpler, all-keys-lost jobs on cars this age are usually more straightforward than on late models.

Key options for the 2007 Chrysler Sebring

• Remote head key. A remote-head key puts two separate systems in one piece: a cut blade with a transponder chip that the immobilizer reads, and a small circuit board with buttons that signals the body control module to work the door locks. On a 2007 Chrysler Sebring with this style of key, each side is programmed separately. That explains some confusing failures. If the remote stops working but the car still starts, the problem is usually the battery or the remote board. If the buttons work but the engine won't run, look at the chip side. Knowing which half failed tells us whether you need a repair, a reprogram or a whole new key.
• Transponder (chip) key. Transponder chips come in families, such as Texas Instruments 4C and 4D, Philips 46, Megamos 48 and the newer 128-bit AES types, and a Chrysler Sebring only accepts the one its immobilizer was built around. That's why a hardware-store blank that looks right often won't start the car. We match the blank to the vehicle's chip and keyway before cutting. One more practical note: the chip lives in the plastic head, and when that head cracks, the chip can fall out or shift away from the antenna. If the car starts some days and not others, a damaged head is a frequent reason, and replacing the key before it quits entirely costs less than an all-keys-lost visit.

How the Chrysler immobilizer works on the Sebring

Chrysler began fitting its Sentry Key Immobilizer System (SKIS) in the late 1990s, and by the 2001 model year most Chryslers in our range used it. The first wave of keys carried a Texas Instruments 4D64 chip in a head cut for the Y159-family keyway, sold as the Ilco Y160-PT blank. From about 2004 the chip changed to a Philips ID46, and most cars paired it with a remote-head key that put the transponder and the keyless entry buttons in one piece. For 2008 the 300 and Town & Country moved to the fobik, a blade-less remote that turns inside a wireless ignition node (WIN), with a proximity version for push-button start. The 2011 redesign of the 300 added a proximity smart key, and the Pacifica minivan, the 2015–2017 200 and the 2019–2023 300 use fobs with Hitag AES encryption. Vehicles from 2018 on also carry a secure gateway module that limits what aftermarket tools can write. Two models break the pattern: the Mitsubishi-built Sebring coupe uses a 4D61 chip and a Mitsubishi blade, and the Mercedes-based Crossfire uses an HU64 flip key with Mercedes immobilizer electronics.

• There was no 2007 Sebring convertible; the redesigned convertible started with the 2008 model year.
• The JS Sebring's remote-head keys are also listed for the Dodge Avenger and for the 2011–2014 Chrysler 200 that replaced it.

Programming a 2007 Sebring key

Keys and remotes are programmed over OBD-II with the 4-digit PIN; the chip and the buttons on a remote-head key can be learned as separate steps. Supplier listings describe an on-board routine for these years when two working keys are on hand. When all keys are lost, a blade is cut by code or from a decoded lock and both functions are programmed at the vehicle.

Lost every key to your Sebring?

1. Gather your documents and the VIN. Find your registration or title and a government photo ID in the same name. Note the VIN, which is printed on the driver's side of the dashboard and usually on your insurance card. If the paperwork is locked in the car, tell us; we'll open the vehicle first and check it there.
2. 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.
3. Originate a new key from the car. With no key to copy, the cuts come from the vehicle itself. We retrieve the key code through manufacturer channels where possible, or decode a door lock with a pick-decoder tool. Then we cut the blade on our code machine and confirm it turns the lock smoothly.
4. 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.
5. Erase missing keys and add a spare. A lost key's metal blade can still open your doors even after its chip is erased. If the keys disappeared along with something showing where you live or park, consider rekeying the car's door lock cylinders too. We'll also recommend leaving with two working keys, not one.

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.
• 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.
• A spare stored safely at home rescues you from a locked car with the fob sitting on the seat, a key dropped somewhere along a hiking trail, or a fob that stops responding on a busy morning. Keep it indoors, never in a magnetic box under the bumper.

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 Sebring, ask us directly and you'll get a plain answer.

Sebring 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

1. Identify the exact key your Sebring 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.
2. Verify ownership before any work. California holds licensed locksmiths responsible for knowing whose car they're making keys for. We record your name, the VIN and the plate on a work order. If you aren't the registered owner, you'll need the owner's written authorization along with your own photo ID before we begin.
3. 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.
4. Cut the blade on-site. Our van carries a code-cutting machine that handles both traditional edge-cut blades and the laser-cut, side-milled profiles common on newer keys. The blade is cut to the code, then test-fitted in a door lock and the ignition or emergency keyhole to confirm smooth operation before any programming begins.
5. 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.
6. 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 Sebring key

• 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.
• All keys lost or adding a key. On some vehicles, losing the last key changes the programming entirely, from a quick add-key procedure to a full immobilizer reset or a module read on the bench. That extra labor shows up in the price, and it's the strongest argument for keeping a spare in the house.
• Programming complexity and security access. Some immobilizers accept a new key with a few on-board steps. Others need a PIN code, a timed security wait, manufacturer online access, or removing a module to read its data. Every extra layer of security on the Chrysler system adds equipment time and labor to the job.
• 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.

Common Chrysler key problems

• The 2018 and 2019 Chrysler 300 smart keys look identical but carry different transponder chips and different FCC IDs, M3N-40821302 versus M3M-40821302. Ordering by appearance alone leads to a fob that will not program, so match the model year and part number.
• Sebring orders get mixed up often: the sedan and convertible use Chrysler keys and fobs, while the 2001–2005 Sebring coupe uses Mitsubishi-based keys and remotes that fit none of the other Sebrings.
• Remotes bought online for 2004 and later Chryslers still have to be paired to the car. Some cars through about 2010 can learn one at home if you hold two working keys; otherwise it takes a programming tool, and used fobs must be unlocked first.

Tips from a mobile locksmith

• 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.
• Make the spare before you need it. Adding a key while one still works is quicker and less expensive than starting from nothing, and it keeps the simpler programming options available. Good moments are right after buying the car, or as soon as one of your two keys goes missing.
• 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.

Proof of ownership

Not every situation fits the simple case, so here's how we handle the common exceptions. For a leased or financed vehicle, a registration that lists you as the registered owner or lessee works with your ID. If you just bought the car, bring the signed title or bill of sale along with your ID. For a company or fleet vehicle, we need written authorization from the business plus the driver's ID. If the car belongs to a family member, the registered owner should be present or provide signed permission and a copy of their ID. Rental vehicles go through the rental company.
