Security system says wait 3 minutes to start can i bypass system?

Is the security light lit on the dash ? Turn the key to the run position , not start ! Leave the key on till the security light goes out ,about 10 minutes , then turn the key off an wait a couple minutes . Then start the vehicle . If it doesn't work you'll need to take it to a repair shop ,have codes read an go from there ! Or you can bypass the system , that involves find the right wires an soldering in a resistor of the proper resistance . You can google how to do a bypass on GM anti-theft system .

You can try this re-learn procedure, if that doesn't work you will need to bypass the security system. I hope you bought the wire harness adapter for that vehicle. They need it.

Perform the re-learning procedure

1. Turn ON the ignition, with the engine OFF.
2. Attempt to start the engine, then release the key to ON (vehicle will not start).
3. Observe the SECURITY light, after approximately 10 minutes the light will turn OFF.
4. Turn OFF the ignition, and wait 10 seconds.
5. Repeat steps 1 through 4 two more times for a total of 3 cycles/30 minutes
6. The vehicle is now ready to relearn the Sensor Data Code and/or passwords on the next ignition switch transition from OFF to CRANK.
7. Start the engine (the vehicle has now learned the Sensor Data Code and/or password).

Sounds like a problem with the security. It immobilizes the fuel injector circuit when the security is on.

Try this: turn key to on, and wait several minutes (up to 30 minutes) to see if light stops blinking. If it does stop, turn key back off, then try to start it. If the security light goes off, it may have reset. If it does not stop blinking or staying on steady, the dealer will charge outrageous prices to fix it-possibly over $800. Google "passlock bypass" or "passkey bypass" or "VATS bypass" to see your options. A site called newrockies sells a module (about $200) that forever bypasses the whole security system.

you have to take key out wipe it off and wait 3 minutes before trying to start again

The Passlock system is notorious for failing. There are 3 different parts of this system that can shut down the car and activate the Antitheft security system. The problem will be one of these 3 things. The key. the ignition lock cylinder, or the TDM. The easiest one is the key. The key will either have a small black chip in the key shaft or a transponder hidden in the key head. If there is a chip, they are known for wearing down and not reading correctly. Try wiggling it, cleaning the chip with alcohol, and taking all other keys off the key chain because it pulls on the key and causes problems. If you have no chip and instead a transponded key, (it will have a little "+" sign by the plastic) you can try performing a relearn procedure. It goes like this.




1. Perform a security system relearn.
2. Let the vehicle sit for more than 10 minutes with the key off.
3. Attempt to start the engine, leave the key in the run position monitoring the security system indicator.
4. After 10 minutes, the security indicator will change state.
5. Turn the key off and wait 10 seconds.
6. Attempt to start the engine. If the engine stalls, wait another 10 minutes with the key on.
7. After the second 10 minute timer has expired, turn the key off for 10 seconds.
8. Attempt to start the engine. If the engine stalls, wait another 10 minutes with the key on.
9. After the 3rd 10 minute timer has expired, shut the key off for 10 seconds.
10. The security system will relearn on the 4th starting attempt and the engine should start and run.
If that doesnt work, you will need to start replacing parts. Like i said, there are 3 parts. The key, the ignition lock cylinder, and the Theft Deterrent Module (TDM). all of these are involved in the Passlock system and could be responsible for shutting down the vehicle. And trust me they are all expensive. I always share this link for this problem because there is so much information on there and will be helpful no matter what you decide to do. If all else fails, there is PERMANENT FIX for this problem. You can bypass all aspects of the system and never worry again. That is also on this link.

If this doesnt work, you may have a failure in your system. If the security light is on, and the reprogram doesnt work, you might want to look into bypassing that antitheft system.

You will have to wait the three minutes. During that time clean the key with an alcohol pad. Works for me.

you might have a worn out resistor pellet in your ignition key and the cars security system senses this and puts the car in a passive bypass mode...usually about 10 minutes before it"ll allow a restart...have the resistance check done on your key a locksmith. they can make you a new key. a good recognized key should reset the system...if this doesnt work then it"ll probably be the security computer system that is going bad.

I experienced this problem, intermittant failure to start. This procedure must be done with the truck RUNNING.

Remove the cover off of your ignition switch. On the top there is a small wire connector that, once the truck is running, should be disconnected. This will turn on the 'SECURITY' light. All will be better, except the security light will be on at all times, much cheaper than replacing the ignition switch, however.

There isnt a fuse for the theft system. You need to take the coloum cover off. Should be 3 screws and you will see all the wires in there. The ones you need are three togather. White Black and Yellow. Get the car started and cut the yellow wire. The theft light will come on and stay on but will bypass the theft system. If it is a 2 wire system you will see two little metal strips on the upper side of the key. You have to use a ohm meter and measure the resistance of the strip in there. Its a resistor used to tell the theft computer the key is in there. Anyway find out what the resistance is and buy a resistor from radio shack and look under the steering wheel for the 2 very small guage wires in a yellow cover....NOTE not the air bag wires. Simply cut those wires ( the 2 white ones) and on the set going away from the steering wheel strip the wires and put the resistor one one wire and the other end of it to the other wire....That will disable that system. If its the 2 wire and you have issues getting it simply take the car to a car audio place that does remote starts and for a nominal fee they will do it for you. My records show that it has the 3 wire system.
