Hoping one of the many anoraks on here can help. My T3 (T25/vanagon/call it what you will) has N profile keys. Think they were used from mid 80s onwards. I have had fitted an alarm/immo in conjunction with factory central locking so have modern VW flip/blade type key shells. I have found someone who can cut N profile keys then carefully dremel them down to fit the shells and turn them into a blade key. I am wondering if anyone knows of a supplier or alternative vw key blade that can be used (HV, HU66 etc) as some profiles appear to be the same but with just an extra groove in the length that has no consequence. thanks
