Re: how to bypass faulty passlock systems

ponchonutty, based on what they said on the last page found on the link below, I've been trying to figure out the practical aspect of wiring a resistor in. They explained the theory but it didn't help so much for the real world of finding the right wires to solder the resistor into. Your method worked great, thanks.

If any of you are wondering about whether you should do this method or the "putting a switch in the wire" trick, I'll let you know what my experiences were.

First of all, both methods do work. I ran my car for a few days with the wire cut while I was trying to figure out how to finish the job with the resistors. Secondly, in my opinion cutting the wire is way easier. It's kinda annoying having the light on the dash, but other than that it's by far a simpler fix.

You may have read about having to re-enable the system if you lose battery power. This is also true. During those few days where I was driving with the wire cut, I really wanted to just leave it that way. I didn't want a battery failure to cause me to have to tear the dash apart and reconnect the two wires. So to test it while it was still torn apart, I disconnected the battery for a half hour and then tried to start it again. No luck. Disconnecting the battery does indeed reset everything and the only way to restart the car again was to just reconnect the wires and hope that the ignition cylinder was able to put the right signal out at least one more time.

So the solution is a switch so you don't have to tear the dash apart again? Right. Except for two things. One is the annoying security light all the time. The more severe is what would happen if you don't lose battery power for a year. You've been driving every day and the ignition cylinder components, while being bypassed, have still been being used every day and have been getting in worse and worse condition.

You find that you have to replace your battery one day so you do. You start your car and crud, the security light starts flashing again. Oh well, flip the trusty switch, wait 10 minutes and try again. Hmmm. It's flashing again. Well, it just must have been one more isolated case of the system not working. Give it another 10 minutes.

Six hours and 36 tries later you've still got a flashing security light and the only solution is to go buy a 300 dollar ignition cylinder so that you can finally get a good signal to the cars computer again before you can even bypass the system again.

I figured I wanted a permanent solution so that's why I went after the resistor method. So far I've been very happy.

My car was giving me problems three or four times a week before I put the resistors in there. Sometimes it would do it twice in a row. When it did actually start the security light would usually come on halfway through the trip I was making. Since I installed the resistor I have not seen the security light even once, either while starting or enroute. Thanks again for the great info ponchonutty!
