How do you replace the pass-key II for the 1995 Buick LeSabre?

Answer 1

The key for the "Pass-Key II" is simply a GM VATS key. The chip is actually just a resistor with one of 15 possible values (the resistance determines GM's numerical value). Any GM dealer, locksmith, or better-than-average hardware store should be able to determine which resistor value your key employs and replicate the cuts onto the appropriate blank. As far as the ignition lock itself (if that's what's going bad), I don't know how to replace it. However, if you want to go the cheap, and sometimes annoying route, you can just wait for the security system to just die. While it's dying, it'll occasionally trigger the Pass-Key system and kill your ignition system for a few minutes. But, once the system finally dies its final death, any key cut with the correct cuts will start your car (basically eliminating the need for the resistor in the key).
