[Slavik386]

Hi everyone. Got few elctrical issues with my 95 vr6 passat. Ok got "enforcer" keyless entry put in this morning, took the car back from the shop found that left lowbeam quit (bulb is fine tho) when engine is shut off the right one wont turn on either The front passenger door lock stuck in lock position and wont unlock Tried to unlock it with the key it worked but locks right back when you tryin' toget the key out (lately got door handle and latch replaced on that door) I'm gonna take it back to the shop and try to get em fix all that but still any ideas????? I just dont get it what you should do to get it all messed up if you just puttin keyless entry in.
Thanks in advance any suggestions will be greatly appreciated
