Security light on dash flashes continually

Asked by Rick Mar 09, 2020 at 11:13 AM

Question type: Maintenance & Repair

I recently had spare key cut. Locksmith connected
something electronic to car but couldn't make
buttons on key work. He also couldn't make
security light on dash stop flashing. Said I should
disconnect battery wait 30 min. and system would
reboot.  I did that but light keeps flashing, even
when car is running. Now something is running 1
yr. old battery down. Dead 2 days in a row. What
can I do?
