2 out of 3 entry locks have failed on my 2002 CR-V so I have a new set coming from Majestic. The problem is well documented in the 2002, Sidewinder cylinders I have read. The only way to get matching locks was to buy a whole set including ignition, which is working fine for now. In fact, the rate of ignition failure is considerably lower that that of the doors. Does anyone know if the two are sourced, or constructed different? With the immobilizer does the ignition cylinder even need tumblers like a door lock? Also, is the immobilizer self contained in a plug-and-play fashion, or will a trip to the dealer be required if I swap it? I am really not looking forward to getting into the steering column.
