2013 Fiat 500e Key Replacement

2013 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 2013 500e

2013 was the first model year of the 500e First generation (Mexico-built). Early-production cars sometimes use different part numbers than later ones, so for a 2013 Fiat 500e we confirm the exact key from the VIN or the old key's FCC ID before cutting anything.

At roughly 13 years old, a 2013 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 2013 Fiat 500e

• Flip (switchblade) key. When a flip key is lost rather than broken, the replacement starts from scratch. For a Fiat 500e, we confirm the FCC ID, frequency and chip type from the VIN and any remaining key, cut the blade by code, then program both the transponder for the immobilizer and the remote buttons for the doors. Some platforms accept a new flip key through the OBD-II port in a single session; others need a security PIN or a module read before they'll take a new key. Aftermarket flip keys vary a lot in quality, especially the hinge mechanism, so we'll tell you which options we trust for your 2013 500e and which we don't.

How the Fiat immobilizer works on the 500e

Fiat returned to the US for the 2012 model year, and every Fiat sold here since has a transponder immobilizer that must recognize the key before the engine will keep running. The Mexican-built 500 and 500c use a Philips ID46 (Hitag 2) chip in a three-button flip key, paired with a Delphi-type body computer. The Serbian-built 500L uses the same chip family but a Magneti Marelli-type body computer, so its remote is not interchangeable with the 500's. The Italian-built 500X steps up to AES encryption: a Megamos AES chip in the early flip key and Hitag AES in the push-button smart key, which is the only style Fiat's owner's manuals describe from 2017 on. The 124 Spider is the outlier, built by Mazda in Hiroshima with a Mazda-designed smart key running at 315 MHz. The first-generation 500e shares the 500's turn-key setup, while the 2024 and newer 500e uses a newer Stellantis keyless system. On the 500, 500L and 500X, the mechanical blade is the SIP22 laser-cut profile. When the chip isn't recognized, the blade can still turn the ignition, but the immobilizer will not let the engine run.

• 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 2013 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?

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. 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. 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. 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

• 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.
• 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.
• 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.

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 Fiat 500e, ask us directly and you'll get a plain answer.

500e key battery

Most fobs for a 2013 Fiat 500e open along a small slot in the seam; a coin or a plastic pry tool works better than a screwdriver, which chews up the housing. If the fob hides a mechanical blade, slide it out first, since the case often opens from that gap. Note which side of the old cell faces up, swap in a fresh CR2032, and press the halves together until they click all the way around. Handle the new battery by its edges, because skin oil on the faces can hurt contact. In most cases the fob keeps its programming through a battery change, so test lock, unlock and start, and you're done.

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. 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.
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.
• 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.
• 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.
• 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.

Common Fiat key problems

• 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.
• 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.
• Buying the wrong remote is a frequent mistake. The 500 and 500c use Delphi-type remotes marked LTQF12AM433TX or 2ADFTF12AM433TX, while the 500L uses the Marelli-type 2ADPXTRF198. The blades match, but the buttons only work on the right car.

Tips from a mobile locksmith

• On any vehicle with a turn-key ignition, keep the key ring light. A heavy cluster of keys, tools and charms swings with every bump and slowly wears the ignition wafers and the key itself. When the key starts to stick or needs a wiggle to turn, deal with it early, before it stops turning entirely.
• 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.

Proof of ownership

Making car keys is regulated work in California. Locksmiths are licensed and overseen by the Bureau of Security and Investigative Services under the Locksmith Act, Business and Professions Code section 6980 and following, and Julian's Locksmith holds company license LCO7891. Verification protects you more than anyone: a locksmith who will make a key for whoever asks will also make one for someone who wants your car. We record your name, the vehicle and its VIN on a work order, and we politely decline jobs where ownership can't be established. You can look up our license at search.dca.ca.gov.
