Chrysler Key Fob Replacement: Cost, Options, and Programming
A Chrysler key fob replacement typically costs about $150 to $350 through an automotive locksmith and about $250 to $500 at a Chrysler dealer in 2026, including programming. A Pacifica smart key sits near the top of that range, older PT Cruiser and Town & Country keys near the bottom, and the Mercedes-based Crossfire is a special case.
Most Chrysler vehicles share the Sentry Key immobilizer and fob designs used by Dodge, Jeep, and Ram, so replacement keys are easy to source and most locksmiths can program them. The exceptions are the Crossfire, which used Mercedes-Benz-derived hardware, and newer models with a security gateway that limits aftermarket tools.
This guide covers Chrysler key types by era, the battery each uses, reuse rules, and when to choose a locksmith over the dealer. For brand-by-brand price context, see how much a new key fob costs.
Chrysler Key Fob Replacement Price by Model and Key Type
| Model examples | Key type | Locksmith (typical) | Dealer (typical) |
|---|---|---|---|
| PT Cruiser, early 300, older Sebring | Transponder key + separate remote | About $80-$180 | About $120-$250 |
| Town & Country, 300, 200, Sebring (late 2000s-2010s) | Fobik that plugs into the dash | About $150-$300 | About $250-$450 |
| Pacifica (2017+), Voyager, later 300 trims | Proximity smart key | About $200-$350 | About $300-$500 |
| Crossfire (2004-2008) | Mercedes-derived key | Limited availability; quotes vary widely | Varies; parts may be scarce |
Year ranges overlap because Chrysler changed key styles by model and trim. Your owner’s manual or the FCC ID on the fob confirms which you have.
Chrysler Key Types by Era
Transponder keys with separate remotes
Through the 2000s, many Chryslers, including most PT Cruisers, used a cut transponder key paired with the Sentry Key Immobilizer plus a separate keyless entry remote. Many of these allowed customer programming of an additional key when two working keys were on hand.
Fobik keys
Starting in the late 2000s, the Town & Country, 300, 200, and others moved to the Fobik: a rectangular fob inserted into a dash ignition slot, with an emergency blade inside. Vans often have extra buttons for the sliding doors and liftgate. The Volkswagen Routan, built by Chrysler, used the same Fobik family.
Proximity smart keys
The Pacifica, launched for 2017, and later push-button models use a proximity smart key with keyless entry and start. Pacifica keys commonly carry sliding door, liftgate, and remote start buttons, so match the button count when ordering.
The Crossfire exception
The 2004-2008 Crossfire shared much of its engineering with the Mercedes-Benz SLK of that era, including its key system. Replacement keys and programming are less common than for other Chryslers, so call locksmiths who specifically list Mercedes-era support before you visit a dealer.
Chrysler Key Fob Battery
Fobik keys commonly use a CR2032 coin cell, and many Pacifica smart keys do as well. Older separate remotes vary by year. If the fob works only at close range or intermittently, replace the battery before you buy a new fob. Instructions are in our Chrysler key fob battery replacement guide.
Model Notes: 300, 200, Town & Country, and PT Cruiser
Chrysler 300: Early cars used a separate remote, later cars a Fobik, and many later trims a proximity key with push-button start. Look at your ignition: a slot means Fobik, a button means smart key. Remote start versions have an extra button, and the replacement must match.
Chrysler 200: Earlier 200s generally used a Fobik. The redesigned 200 offered keyless go on many trims, so check for a start button before ordering.
Town & Country: Most used Fobik keys with sliding door and liftgate buttons. Button count varies from about four to seven, and a fob with the wrong layout will not control the power doors even if it starts the van.
PT Cruiser: Typically a cut transponder key and a separate remote, which makes it one of the cheapest Chrysler keys to replace. A basic chip key can often be cut and programmed by a locksmith in a single short visit.
Whatever the model, the FCC ID and part number printed on the fob or its circuit board settle compatibility. Our guide on finding the FCC ID on a key fob shows where to look.

Can a Used Chrysler Fob Be Reused?
Generally not without extra work. Chrysler-family Fobiks and smart keys are typically locked to the first vehicle they are programmed to. Some locksmith tools can unlock or renew certain fobs, and a used fob may still be able to control the locks on another vehicle without starting it. Treat used fobs as risky unless your programmer confirms they can use that exact part. More in reprogramming a used key fob.
How Chrysler Key Programming Works
- Older vehicles with two working keys: Many supported customer key programming using an ignition sequence. The owner’s manual lists whether yours does.
- Fobik and smart key vehicles: A scan tool and the vehicle’s 4-digit security PIN are normally needed.
- Newer vehicles with a Secure Gateway Module: Many Chrysler-family vehicles from around 2018 on require an authorized tool login or a bypass for key programming.

Dealer vs Locksmith for Chrysler Keys
For Fobik-era Town & Country, 300, and 200 vehicles, a locksmith is usually the better value. For a Pacifica with all keys lost, call ahead to confirm the locksmith can handle the security gateway. Chrysler shares hardware with its siblings, so our Dodge key fob replacement and Ram key fob replacement guides follow the same logic.
