Making Key Fobs
keys
Yes, you can have two different key fobs together and use them interchangeably for the same vehicle. Each key fob will have its unique code that the car's system recognizes, allowing multiple key fobs to be used with the same vehicle.
Typically, key fobs are not designed to be combined with each other. Each key fob is paired specifically to its corresponding vehicle or access point. If you have multiple key fobs for different vehicles or places, they should be kept separate for proper functioning.

Most (if not all) key fobs can be recoded. You may want to inquire with your dealership or a good locksmith.

To reprogram the key fobs for a 2005 Jaguar XJR, first, ensure you have all the key fobs you wish to program. Insert the key into the ignition and turn it to the "On" position without starting the engine. Within five seconds, press and hold the lock button on the key fob for about 10 seconds, then release it. Repeat this process for any additional fobs, turning the ignition off to complete the programming.
