I have a 2003 Buick Lesabre...My problem is with the anti theft security system on my car....I left the lights on my car all night by accident...the next day it would not start...so I removed the battery from my car to recharge it...That's where my problem began...I thought it was the battery but it wasn't...that battery is brand new! The car would not start ...it would not recognize the key...I'd like to know how I can reprogram the car to get it to start again...I'd appreciate any help...Thank-you

You have a coded key for your ignition. If you have another spare key-- try starting the car with that one and see if it works. You may need to disable the Anti Theft Security on your car. check out this video about deactivating Anti Theft Security System on your car. https://www.youtube.com/watch?v=rrRbPdPlecg
If you mean the anti-theft PASS system, it does not work that way. You have to have power to the module, and it has to get the right signal from the key chip to start the engine. Otherwise a car thief could start the car.
It is common for GM's vehicles to stall due to the anti theft security system. Look for a light that says "security" the next time it stalls. If you see this light, check out this link for options and info.
This might be the anti theft security system. when this happens, look all around the dash for a light that says "security". One of the symptoms of a failed GM anti theft is....... Starts for 1-5 seconds and then stalls. If this is the case, check out this link for info on the problem and "do it yourself" solutions. http://vatspasslockpasskeysecurityhelp.yolasite.com/
