Question about 1994 GMC Yukon
Lights were left on in morning. It has an Astro Start but now it will not start. If you push button, the lights come on as it did just before it would start, but does not start. Then lights go off. Battery has a full charge and you can start it with key in the ignition with no problem.

SOURCE: Key will not unlock door
the lock on the driver side could be damaged or some on might have used a jimmy to open that door before how evr you have to open the pannel and remove the lock cylinder part and make sure that the key is working or yo must change the tumbler s in the lock to fit your key (lock smith)

If the bat went dead and was disconnected it can take 25 to 50 miles of driving for computer to reset sensors and controls. Sounds like MAF Sensor maybe reading different than when it was first driven. Did you drastically change climates or altitudes, New readings from when it originally was put into service. Slight changes in temp, alt and other variables gradually reset, if driving does not improve within 50 miles it will need diagnostics.
