Having problems with your 2003 Toyota Corolla ?
I have a 1999 Toyota Corolla and electronic key system has only locking button. The unlocking button is lost and I was told I need to buy one online. Last night after coming home I have locked with electronic locking button and doors got locked. Today I have opened the door manually with the key and tried to start the car. It automatically triggered the theft alarm and red light besides steering is blinking continuously. It disable the car starting. The alarm comes only when we try to ignit
I am having the SAME problem with my 99 Corolla, Still searching for a way to disable the factory security system, for the last two years I have the vehicle hotwired through the headlights to start it. (1 wire to battery positive, 1 wire to starter hot lead, touch them together.) unfortunately this has proven very dangerous as the vehicle will start even in gear, and take off without a driver. additionally, because the alarm is going off continuously, the battery dies if not disconnected after every use. I found the fuse in the relay box that disbles the alarm, and the car starts fine, unfortunately, It it also the fuse for the alternator, so that solution will not work either. If anyone has found true way to disable the system, PLEASE offer your suggestions!
Swap the efi relay with same relay in engine side fuse compartment. should works 100%
