Have replaced the batteries in both keys but still won t re program Are the keys generally reliable ? It's a 2004 done approx 125000 miles

Think so guess I m wondering if there is anyway of checking if there is a signal coming from the key without connecting to diagnostic

Have managed to reprogram one of the keys numerous times but recently unable to reprogram have tried all the various sequences out the to program Any suggestions welcome Thanks

Just purchased a RR vogue Lovely car but got a feeling I'm gonna need a bit of help in keeping it going !!
