S10/S15 Disable DRL and Electronic Key?

You're probably gonna do a lot of cussing. My 99 has automatic headlights and they are "difficult" to make back to manual. If your daytime running lights are seperate, simply pull the fuse. If they are part of the high beam system, pull the relay. I think the electronic key is still just an option. The way I read, you can't disable thing at all. You can't even change the entire ignition switch without it.

You will find various posts about ways to abort or work around those keys.

My kid has a Olds 88 with a chip in the key. One of his keys doesn't work. Its a resistor type of thing that when inserted becomes a proximity chip. If the resistance doesn't match, the key won't turn. You're right, of course. There are ways to beat it. Its just not very feasible for the average shade tree guy. Its all wired through the computer system and since its part of an anti-theft circuit, it is difficult to just bypass the damn thing. I'm sure that it doesn't even slow down a crook, but it sure as hell confounds the consumer!

Depends on the year there were different systems of theft prevention. Usually they can all be bypassed with a simple module designed to work with a remote start systems.
