2023 Dodge Grand Caravan key fob.

OEM & aftermarket part numbers

The 2023 Dodge Grand Caravan ships from the factory with a integrated transponder fob identified by the OEM part numbers below. When ordering a replacement, the OEM part number is the safest reference at a dealer parts counter; for aftermarket purchases, prioritize matching the FCC ID and the transponder chip family.

Aftermarket fobs for the 2023 Dodge Grand Caravan typically run $25–$60, while OEM units from a Dodge dealer cost $120–$220 for the same hardware. Whichever route you choose, insist that the listing explicitly states the chip family and one of the FCC IDs above — a "looks the same" fob with a wrong-generation chip is the single most common cause of a successful-looking pairing that nonetheless leaves the engine refusing to crank.

Button configuration

The OEM 2023 Grand Caravan fob carries the following buttons. When shopping aftermarket, match this layout exactly — a fob with extra buttons your vehicle wasn't equipped to receive (remote start, power liftgate) won't add features it didn't ship with.

Transponder chip & immobilizer

Hitag-PRO is the modern AES-128 successor to Hitag2. Used heavily across late-model Ford, Lincoln, Mopar, and select Subaru proximity vehicles. If you're sourcing a replacement, look for chip family "PCF7953 (Hitag-PRO)" on the listing. Generic descriptions like "fits 2010-2020 trucks" without naming the chip are red flags.

Aftermarket programmer compatibility

Below is the compatibility table for the chip family used in the 2023 Grand Caravan. Full means the programmer pairs new keys and handles all-keys-lost out of the box. Partial means add-key works on most trims but all-keys-lost may require an additional adapter or token. Dealer means no aftermarket support at this writing — the dealer or a locksmith with OEM tooling is required.

Pairing notes for this model year

The 2023 Grand Caravan uses an AES-128 secured chip (PCF7953 (Hitag-PRO)) that requires a programmer with the correct license to read the vehicle's security PIN over OBD-II before it can pair a new fob. Onboard ignition-cycle and door-lock procedures will not succeed on this vehicle — if a YouTube video tells you otherwise, the procedure was almost certainly recorded on an earlier model year that used a different chip.

Two practical paths: (1) call a mobile automotive locksmith with one of the "Full" programmers above (typically $120–$220 plus the cost of the fob itself), or (2) take the vehicle to your Dodge dealer ($200–$420 plus tow if you have no working key). The locksmith almost always wins on convenience and total cost.

Verifying the fob is paired

After pairing, walk ten feet from the vehicle and test all of the following from the new fob: lock, unlock, panic (if equipped), and trunk or liftgate. Each should respond on the first press. Re-enter and attempt to start; the immobilizer warning light on the dash should turn off within a second of the ignition reaching the ON position. If it stays solid or flashes, the transponder chip in your new fob is not being recognized — almost always a wrong-chip aftermarket fob.
