This listing is NOT to repair or replace a faulty M534, that is our other service. This service is to add a new remote key(s) to a known working M435

Does your Porsche have only one remote ? Then this is the service for you.

By sending us your M534 unit (located under the front left seat .. we would say passenger but it depends which side your steering wheels on!) and your existing key, we will return your unit with an additional fully working remote key.

This service can only work with clean functioning M534 units.
