The alarm set caution light on s flashing where the other warning lights are it just says alarm set
Expert:  Robert R replied 8 months ago.

Ok, I'm a bit confused about your aftermarket keys. Do they turn the door lock cylinders and will they turn the ignition switch to the Run position??

Did you try to insert the keys into both front doors and lock and unlock manually to see if the alarm will turn off?

Keep me posted...

Thank you,


Customer: replied 8 months ago.
they both turn the ignition on and off but neither will operate any of the door locks
Expert:  Robert R replied 8 months ago.

Ok, There are a few options on this...

First, you can remove the driver door inside panel and look for the door alarm switch that is attached to the back side of the door lock cylinder. you can remove this switch and manually activate it with a screwdriver. This should shut off the alarm. There is no code that can be entered that can turn off the alarm. Another option is to purchase a remote keyfob and tow the vehicle to your local dealer and have them program this fob to your vehicle to be able to operate the keyless entry to unlock the doors and turn off the alarm. The last option is to go to your local dealer and purchase a "valet" key and have them cut the key for you from the original key code that came with the vehicle. The dealer should be able to cut a key that will unlock the doors from the original key code as long as the door lock cylinders have not ever been replaced... This new key should at least be able to unlock the doors and turn off the alarm. It won't likely work the ignition since it appears that the ignition lock cylinder has been replaced with aftermarket...

Keep me posted and let me know if you have any additional questions...

Thank you,
