Hello Ah-Kay,
On my 1984 300SD the drivers door handle has a wire going to the key mechanism, but the trunk lock and the passengers door lock do not. By this I mean if I put the key into the drivers door and unlock it Everything unlocks, all the doors, trunk, and fuel filler. If I unlock the passengers door or the trunk with the key nothing else unlocks.

Will this keyless system work with my vehicle? The vacume/pressure pump is in the spare tire well.
