Question about GMC Vehicle Parts & Accessories

1 Answer

My 2000 Yukon Denali will not start. I suspect the security system because there isn't a problem with the battery. Turn the key and nothing happens. Can I reboot the system or is this possibly just an ignition switch issue?

Hi. You can reset the security system by detaching the negative port of your battery and then put it back. You can test also the ignition if it is bad by turning the headlights on then turn the key to start position. Headlight should go dim if the ignition is good. If nothing happens to the headlight when you turn the key to start position then you have a bad ignition.

I have a 2000 Yukon Denali and the alarm system will not alow it to start at times.....What should i do whwn this happens or how can i prevent this from happening


According to my lists, 2000 Yukon has a Passlock 2 anti theft security system. This means that the key literally has a transponder in it that sends a radio signal to the ignition. The ignition/lock cylinder then sends a signal to the TDM (theft deterrent module) which then reads the signal and allows your truck to start. If there are any communication breaks, the truck thinks its being stolen and goes into anti theft.... Read up on this link. There might be an option for you. http://vatspasslockpasskeysecurityhelp.yolasite.com/

I bought a wrecked Denali hooked the battery up and everything just keeps flashing is there a reset for the system or is this another problem


sounds like the security,if you got a key fob,use it (assume u would have done that)
Try locking then unlocking the drivers door from the outside with the key,should turn the system off

Removed/charged @ reinstalled battery, security light & security system won't shut off,key won't start car or even turn over


Because you disconnected the battery you have set the security system on and it will have to be reset. Try putting the key in and leaving it in the on position for 20-30 minutes, shutting truck off and then try restarting. Short of that you may have to call the dealer.

We had the same issue with our 2007 Yukon Denali XL. Died on us twice after sitting for short periods of time; once we watched a DVD with the engine off and battery died within 10 minutes. The dealership kept it overnight to troubleshoot why the battery died so quickly. They said the radio was "pulling" too much from the battery. (They supposably fixed it) But again a few days later the battery died again after sitting overnight. We brought it back to the dealership and they brought in a GMC "expert" to replace the entire DVD/CD/Navigation system. They also replaced our battery with a much larger battery, similar to the ones that GMC puts in there diesel trucks. They had our Denali for 5 days, but it appears to be fixed now.
Getting it fixed correctly wasn't without headaches, but it was all covered under warranty, including the battery. And they are updating the nav w/ the new edition disc as well for no charge.

you have a bad ignition switch but if you turn key on for ten minutes until the light stops flashing then turn off key then try to start this should reset the security system
