I've got a '05 R52 JCW
which all works fine apart from the remote locking. I've had it into an indie who reckons the keys are fine, but the Body control unit is at fault. Rather than spend £400 on a new one (mebbe just to find the receiver is at fault) I've got a 2nd hand one from a '05 r53 for £20 off fleabay - can it be swapped in and then the keys programmed by the ignition on/off hold buttons down etc, or does the new BC1 have to be assigned by an autologic or summat?
Would it do any harm to swap it in and test?
any help really appreciated.
