TRW has made many different styles of keyless entry remotes for Chrysler, Ford, GM, Toyota and other manufacturers. One of the more distinctive of these — due to its shape and button configuration — is a remote with FCC ID GQ43VT18T made for Chrysler and used on 2001-04 Chrysler Town & Country, Dodge Caravan and Dodge Grand Caravan vans that had dual power sliding doors and a power lift gate.

This remote is user programmable if you already have a working remote. If not, programming requires a special computer tool, so you will have to take your vehicle and all new remotes to be used with the vehicle to a dealership for assistance.
