My 1995 town car has the original factory code (that will always work) on a label in the trunk. I found it on a label applied to the inside metal of the left fender inside the trunk (and I had to pull the trunk liner loose to find it.)
But I have seen many others post they have found the label with orig code on their trunk hinge. Maybe it comes both places and someone prior to me buying the car had removed the hinge-mounted label.
Somthing in denmark stinks..........
Each vehicle that has keyless entry has its own code
Each vehicle has it's own factory keyless entry code
yes they do, i have it on mine.
My 1999 has it, so likely yes it was available in 2001
To change the setting on the keyless entry for your 2001 Blazer, first, locate the keyless entry transmitter. Insert the ignition key and turn it to the "On" position, but do not start the engine. Press and hold the "Unlock" button on the transmitter while simultaneously pressing the "Lock" button three times within five seconds. This should reprogram the keyless entry settings; test it to ensure it works properly.
You should have programming instruction in the user manual.
To determine if your 2001 Buick Regal LS is equipped with keyless entry, check the owner's manual for features listed under "Remote Keyless Entry." Additionally, look for a key fob; if your vehicle has a fob with buttons for locking and unlocking the doors, it likely has keyless entry. You can also inspect the driver's door for a keyless entry keypad or observe if the doors lock/unlock as you approach the vehicle with the fob. If you're still unsure, contacting a Buick dealership with your vehicle's VIN can provide definitive information.
the batterys in your keyless remote may need to be changed
A keyless entry remote on a 2001 Toyota Sequoia can not be reprogrammed at home. The key must be taken to a dealership where the engineers can program it with new settings.
You can program the keyless entry remote, for your 2001 Saturn L200, by holding the unlock and lock weapons at the same time. The red light will flash on and off. The remote will be programmed when the red light stays illuminated.
Unplug battery for 30 minutes then plug back on that will reset the ecm
