Saab Problems? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here. Replacing the TWICE unit will likely solve the problem your having but it will require programming. You may want to check with your local GM dealer as there are some of them that may be able to do this programming for you.
Im not sure the old unit can be repaired but that would be something for a lock smith to look at. Im not sure what caused the old lock to fail beside just wear.
I will open the post back up for you and perhaps another will have what you need.
