Hey Everyone I have a GM Good Wrench Vehicle Security System 100 circa 1988. I have recently acquired the installation instructions but found the instructions for programing the 3 digit code were not included. Apparently it was a accessory module that was not part of the basic system. Does anyone know how to program the key pad? (looks just like a telephone key pad) Thanks a million.

This could be obsolete information, but the company that manufactured that system was Code Alarm, and their phone number is (was?) 1-800-421-3209. They are (were?) located in Troy, Michigan. These were dealer installed alarm systems, and were fairly high tech at that time.

VSS 100 (economical)

• starter kill lockout
• hooks up to vehicle horn
• convenient alarm bypass switch
• Optional: 125 decibel waterproof siren, lite touch adjustable shock
• sensor, light flasher, keypad.

I hope this response is consistent with what you hear back from all the other forums you posted this question on.

Here is their website:

Thank You for the information! I will call them first thing monday morning. It took me over a year to find the instillation instructions. But with your info i think will be more like week now! Thank a million......

You are very welcome. I took a look at their website and there is a spot to download manuals if you know the exact model number. Also, the phone number I gave you is correct.

Please let us know how you make out in resolving this. Other members may have the same issue at some point, and your experience may help them.

I just got off the phone with code alarm. The vss100 key pad is hard programed with a 3 digit code that can not be changed. I was lucky the code is taped on the unit it self. I also scanned the installation and operation instructions in to a PDF file. For anyone that needs them.

I'm glad it worked out for you. Now you know where to come for all your Bonneville questions.

I installed the system today and it works Great!!

Thank you for providing this answer here it is really a nice one for me.
