Believe it to be factory. Standard key ( no keyless remote ).

Ok is the vehicles battery fully charged?
Customer: replied 3 years ago.

It was.Many attempts and opening of doors as well as continual rapid flashing of anti theft light on dash. Interior lights, power locks working. Looks like just shy of 12 volts on dash meter now.

Oknthats will cause this issue as well as dead cells in that battery hoe old is the vehicles battery?

Replaced with NAPA 75 battery and still no difference. Noticed meter on dash read the same as with old battery. Tried key sequences on exterior doors, hatch again with no luck. Anti theft light is still blinking. Open the door and get sequential beeps, with parking lights flashing 6-8 times. Sure seems like anti-theft issue but I have no idea how it works or how to clear it or over ride it.

Please advise regarding replacing battery with no result.



OK try this for me .Key in ignition with the it turned to the on position where the radio works then disconnect the positive battery terminals for about 30 seconds and rescuer and let me know if the system resets.

Sorry for the delay. I tried the above to no avail. After further inspection with my usual mechanic, it was determined that this is an AFTER MARKET device. He is removing it today and hopefully, I'll be good to go. Thank you for your time and suggestions.

Anytime.Im here if you ever need any further assistance.
