2005 Jaguar X-Type keyless entry

Remote Transmitter Programming
NOTE:All remote transmitters are programmable and must be programmed at the same time.

NOTE:If an attempt is made to program a fifth remote transmitter after four remote transmitters have already been programmed, the generic electronic module (GEM) will exit the remote transmitter learn mode. If the remote transmitter learn mode is entered again, the attempt shall erase all remote entry device associations and start a new set of four remote entry device associations with this fifth remote transmitter programming attempt.

The complexity of the electronics involved with the remote keyless entry, of which the GEM is a part, and the multiplexed communication network which are connected to it, exclude the use of workshop general electrical test equipment. Therefore, reference should be made to the Jaguar Approved Diagnostic System for programming the remote transmitters.
