Diagnostic Aids

WARNING: This page is about a different car, the 1993 Buick Roadmaster. However, it is still accessible from the selected car via links, so may be relevant.

Program a known good transmitter and test keyless entry system. If keyless entry system operates normally, original transmitter was defective. If keyless entry system is still inoperative, replace keyless entry receiver.

NOTE: Test numbers refer to numbers on diagnostic chart.
