How Jeep immobilizers work
Jeep uses the Stellantis (formerly Chrysler) immobilizer family — SKIM and SKREEM on older vehicles, then the RF Hub on newer ones. Both require a PIN before a key can be added. Wrangler, Grand Cherokee, Cherokee and Compass each use different key formats across their generations, and newer vehicles may have a secure gateway module that affects diagnostic access.
No locksmith can honestly promise every Jeep model and year. Whether a key can be made for yours — and where — depends on the year and system. Call (312) 478-6125 with the year, model and VIN and ask before anyone is dispatched. Mr Locksmith is an independent locksmith and is not affiliated with Jeep.
Common Jeep key types
- Transponder key
- Fobik key
- Smart key (proximity)
All keys lost on a Jeep
Jeep all-keys-lost requires reading the PIN from the immobilizer module, then cutting and registering a new key. Model year decides which module and which access route apply.
Worth knowing
Jeep Fobik keys tend to crack where the blade meets the head, and a cracked shell eventually stops reading. Moving the existing electronics into a new shell costs far less than a new programmed key.
Locked out of a Jeep
Wranglers with soft tops and removable doors are often easier to get into than they look, but a locked hard top and tailgate still need the same care as any other vehicle.
Before you call about a Jeep key
- The year, model and trim of your Jeep
- The VIN — visible through the windshield on the driver's side, or on the registration
- Whether any working key or fob still exists
- Where the vehicle is: driveway, street, parking garage level or commuter lot
When the technician arrives, expect to be asked for photo ID and proof of ownership — the registration, the title, or a lease or financing agreement in your name.
Car keys by make

Common questions
My Jeep key fob battery died — how do I start the car?
On push-button Jeeps, press the brake and push the start button with the nose of the key fob — the end opposite the key ring. Fobik-style Jeeps insert the fob into the dash slot like a key, so a dead fob battery only affects the remote buttons.
What does adding a spare Jeep key involve?
Adding a key to a Stellantis vehicle requires the immobilizer PIN and diagnostic equipment; some older models allowed owners to add a key with two working keys, but that does not apply to most current Jeeps. Newer vehicles with a secure gateway module need authorized access before programming.
