ok i found this i guess its what i'm looking for.

Reactivating the fob key:
1 Switch ignition "ON" six times from "LOCK" position within 10 seconds
and return the ignition switch to "LOCK" position.
-- The hazard lights should flash twice.

2 Press and hold the unlock button (black) while pressing the lock
button (red) 3 times.Release the unlock button.
-- The hazard lights should flash once.
When done, turn the ignition "ON"---the hazard lights should flash
twice.

one more question my battery wont recharge i have checked the battery with a voltmeter when the engine was idle and it was 10.03 now i read it should be around 13.5 at idle is this true and is the alternator likely at fault?
Thanks for any help.
