Want to lock doors while warming car up

THE SOLENOIDS MAKE A BUZZING NOISE WHEN THERE IS AN OBSTRUCTION.

You must have a "After Market Alarm" or something similar. The factory Auto door lock system doesn't lock the doors until the vehicle reaches 18 mph approximately.
So what I am saying is the Add-On Door Lock/Alarm System is malfunctioning - however some of those aftermarket systems can be programmed to lock doors with the engine running and Driver's door closed (they assume you will be sitting in the driver's seat at that time) It varies depending on which manufacturer built the system. I have seen on some of those systems they provide a small loopwire on the Module that can be cut to disable the Auto Door Lock feature - you might need the install manual to know which one.

You need to look at the door lock actuators, I'm guessing 1 is operating but staying on when locked and draining the battery. Try manually locking the doors and see what happens. It may come down to removing the door trims and disconnecting each lock in turn, don't forget the boot lock, until you find the culprit. Its possible you may hear the lock solenoid humming or buzzing or feels warm as its trying to lock the door unsuccessfully.

Your original keys had a computer chip in them that is programed to your car's computer and you will have to have a dealership reprogram your new keys to match your car's computer. or if you still have the original ignition lock you can reinstall it and contact your local dealership and give them your car's Vin# which is located on title or vehicle registration. And most dealerships can make you a new ignition key. Then your car should sta

don't have 2 fobs?
it cam with 2,
and the battery must be good.(for buttons to work on fob)
never run any car with only 1 fob or one key.
or get locked out.
are you saying the metal cut key end (pure mechanical ) failed?

my car has a real key with a a transponder inside .
it can open 2 ways, the keyfob buttons, (takes a good battery)
and the key metal end.

now you have 2 like you should.

first most GM OEM systems will need to recognize the key first and foremost ,to do that you will need to roll window down on driver door,turn the key to the run position and with engine NOT running leave the key on for 10 minutes exactly ..then turn ignition off then try to start engine. if original system is working engine should start normally

It appears that you have an electrical short somewhere. If you are mechanically inclined and have hours of time and electrical knowledge, good luck! Sometimes these problems can be easily found where the wiring harness runs through the firewall from the fuse panel under the dash to the engine compartment relay box. Vibrations of the engine over time on a vehicle over 10 years old will chafe the wires over time on places where the wires lay over body frame components. Also heat and time on a cars wiring harness over a decade can damage wiring in the engine compartment or along exhaust manifold underneath. Try looking in those places for visible damage before tearing out all the interior or dash.

Seat belt him in there!! Why wont it run parked with doors locked?

Check and replace fuel filter, also check your fuel pump pressure when the car is warm.

the latch may need to be cleaned from dirt and dust then sprayed with penetrating lube. It does require removing the latch from the door.
