2015 Fiat 500e Key Replacement

2015 500e key specs

The first 500e uses a flip key styled like the gas 500's, with lock, unlock and liftgate buttons, and a SIP22 blade that turns the ignition to switch on the electric drive system. The same remote also locks and unlocks the charge port door. Because far fewer 500e cars were built, replacement remotes are harder to source, and you shouldn't assume a part listed only for the gas 500 fits. Read the FCC ID printed inside your fob before ordering anything, or call with your VIN and let us confirm the correct part first.

What's specific to the 2015 500e

The 2015 Fiat 500e is the third of 7 model years in the 500e First generation (Mexico-built) (2013–2019), so it shares its key system with the rest of that run, which makes replacement parts easy to source.

At roughly 11 years old, a 2015 Fiat 500e has usually seen real wear. Ignition and door cylinders on high-mileage cars wear along with the key, so we cut new keys to factory code rather than copying a worn key. Fob cases crack, buttons wear through and solder joints loosen at this age, so a new shell or a replacement remote often beats repairing the old one. Many have changed hands more than once, so erasing keys you can't account for is worth doing during the visit.

Key options for the 2015 Fiat 500e

• Flip (switchblade) key. A flip key folds its blade into the fob on a spring-loaded hinge and swings it out with the press of a button. Inside the body sit the transponder chip and the remote circuit board, which means the metal blade itself carries no electronics. That's good news when the blade snaps. On many flip keys for a Fiat 500e, we can cut a new blade to your key code and fit it into your existing fob, with no reprogramming required, because the chip and remote never left the housing. Many flip-key blades are laser-cut, with a groove milled along the side rather than notches on the edge, so they need a code machine built for that profile.

How the Fiat immobilizer works on the 500e

• Fiat assembled the first 500e in Toluca, Mexico, from late 2012 until mid-2019.
• Fiat sold the first 500e only in a limited number of states, mostly California, rather than nationwide.
• The key fob's lock and unlock buttons also operate the charge port door, according to the owner's manual.
• A weak 12-volt battery can make a healthy 500e key seem dead, so test it before replacing the key.

Programming a 2015 500e key

Key programming runs through the OBD-II port with Fiat immobilizer software and the security PIN, much like the gas 500. The electric drivetrain adds modules the gas car doesn't have, so we confirm tool coverage for the exact VIN first. We also keep the 12-volt battery supported during the session, because a sagging 12-volt supply is a common reason programming fails on electric cars.

Spare keys are usually possible. With low production numbers, remote availability and all-keys-lost coverage vary by VIN, so we confirm before quoting.

Lost every key to your 500e?

Losing every key is fixable on most Fiats, but it takes more than a cut blade. On the 500, 500c and 500L, we verify ownership, decode the SIP22 door lock or cut a blade from the key code, then connect to the OBD-II port, read or enter the security PIN and program a new flip key. If you kept the code card that came with a new car, it speeds up the cutting step. The 500X needs AES-capable equipment, and some push-button or late-model cars involve extra security procedures that we explain on the phone. The Mazda-built 124 Spider depends on tool coverage for its VIN, and the plate stamped with its key code number helps on the cutting side. For the 2024 and newer 500e, plan on a dealer-supplied fob. Have your ID and registration or title ready, and give us the VIN when you call so we can confirm the route before we drive out.

1. 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 Fiat 500e can be done on-site and bring the right key, so the first trip is the only trip.
2. Get into the vehicle without damage. Entry comes before key-making because we need access to the ignition, the OBD-II port and sometimes the documents in the glove box. We take care with weather stripping, door frames and paint, and we confirm the dash VIN matches your registration before going any further.
3. 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.
4. Program the key to the immobilizer. All-keys-lost programming often takes longer than adding a key, because the car has no trusted key to authorize the change. We follow the procedure your Fiat 500e requires, then confirm the engine starts and keeps running and the remote or keyless functions respond.
5. 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.
• Two drivers sharing one key is a daily negotiation. A second key lets a partner, teenager or coworker use the vehicle without handing keys back and forth in parking lots, and it means one person losing their key ring doesn't leave the whole household stuck.
• Electronics fail without warning. A fob dropped on concrete, run through the washing machine or soaked at the pool can quit for good. With a second programmed key, that's an annoyance you fix on your own schedule, not a stranded car that needs attention today.

Dealer or mobile locksmith?

The biggest difference between a dealership and a mobile locksmith is where the work happens. A dealer programs keys in its service bay, so if every key is lost, the car usually has to be towed there, and you work around the service department's schedule and the time it takes to order a key by VIN. Julian's Locksmith brings the cutting machine, key blanks and programming equipment to the car, whether it sits in your driveway, a workplace lot or a parking structure. For a 2015 Fiat 500e we can program on-site, that means no tow and no shuttle rides back and forth. The trade-off is real, though: on vehicles where only the dealer can program keys, a tow or appointment may still be necessary, and we'll say so before you spend anything on our visit.

500e 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 500e uses. Every job starts with the VIN, the trim and a look at any key you still have. From those we confirm the keyway, the transponder or smart-key chip, the remote frequency, the FCC ID and the button layout. Two Fiat 500e keys that look identical can carry different electronics, so this step keeps the wrong part from ever reaching the car.
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. A key is cut from a code, not a guess. When the factory code can be retrieved through manufacturer channels after ownership is verified, we use it. When it can't, we decode a door lock with a pick-decoder tool that reads the wafer positions without damaging anything, then work out any missing cuts.
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 Fiat 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 500e key

• The type of key. The biggest factor is technology. A plain mechanical key is a cutting job only. A transponder key adds a chip and programming. Remote-head and flip keys add a circuit board, and a proximity fob for a push-button Fiat 500e is the most involved of all, both in the part itself and in the programming.
• 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 Fiat system adds equipment time and labor to the job.
• Blade style and cutting. The blade still matters on keyless cars, because the emergency insert has to fit the door lock. Cutting by code is standard for us. Decoding a door lock when no key or code exists adds time, and so does progressing any cuts the door lock doesn't show.
• Travel, timing and extra repairs. Because we come to you, the distance from our San Bernardino base and the time of the call play a part. So does anything we find along the way, such as a worn ignition cylinder or a seized door lock. You hear about each item and get a quote before we start work.

Common Fiat key problems

• Remote range fades as the CR2032 battery in a Fiat flip key ages, and the battery contacts in cheap replacement shells can lose tension. If a fresh battery doesn't help, the remote may need re-syncing or the board may be cracked.
• A key that turns but won't start the engine usually means the immobilizer doesn't recognize its transponder: a damaged chip, a key programmed to another car, or a spare that lost its pairing. Reprogramming fixes it; the ignition is rarely at fault.
• Inexpensive online Fiat flip keys often arrive locked or uncoded. Many must be pre-coded on a key programmer before the car will learn them, so a key that won't program is often the wrong blank rather than a fault in the car.
• On the push-button 500X, a weak smart-key battery can bring up a key-not-detected message. Fiat's manual says to touch the back of the fob, the side opposite the emergency key, to the START/STOP button, which usually gets you home.

Tips from a mobile locksmith

• When a key's head cracks or its blade bends, replace it before it fails. A transponder chip can slip out of a split head, and a bent blade can break off inside the ignition or door lock, turning a simple key replacement into an extraction and repair job. Small symptoms are the inexpensive time to act.
• 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.
• 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.

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.
