What causing my 2000 Yukon denali not to go in gear

SOURCE: 02 yukon denali security light stays on will not

Several GM products, including the Chevrolet Impala and Malibu, the Oldsmobile Alero, the Pontiac Grand Prix, and Saturn Ion, have issues with the Security light coming on. This is many times an indication of a failing Body Control Module (BCM). Initially, the Security light will come on then go off, progressing to a constant on light, before the car will refuse to start. Other symptoms may include erratic action of electronics, a clicking sound coming from the glove box, and the air conditioning failing to blow cold air. I recommend a shop that specializes in the electronic systems of vehicles to diagnosis and make the necessary repairs. They should keep the car until they replicate the symptoms described. A new BCM from GM should cost about $230; plan on another $200 for them to diagnose the problem, replace the unit, and program the new unit. The dealers quote between $700 and $1,100 for the same repair. My experience and the experiences I have read on the internet, indicate the new BCM should last only about a year.

BCM issues for my 2000 GMC Denali FIXED! I was having body control module issues on my 2000 Denali for months. Never knew when I would put the key in the ignition and have NOTHING happen. Figured out it was probably the BCM not recognizing the key therefore the security system (through the BCM) was shutting down the start capability for a brief period, usually about 15 minutes. Then I would have to go through an exercise of key-on, key-off ******** to get it to start. Well, here is the FREE solution. Leave the freaking key in the ignition forever. NEVER remove it once you get the system to recognize it (when the vehicle starts the key has been recognized). Of course you can simply turn the vehicle off as usual, just DON'T REMOVE THE KEY. Now, if you live in a high crime area (I don't), leaving the key in the ignition may not be a good idea but frankly I would rather have it stolen than keep refusing to start. And you can always lock the vehicle with the key fob (better keep a spare key handy in case your vehicle or the fob loses power). I still have the occasional freaky windshield wiper thingy (won't shut off from the wiper switch) but so what? I've saved tons of money and the vehicle has not refused to start for OVER a YEAR!!! FIXED.
