Try a different key. It may be the transponder chip.

theft light flashing fast

Could try disconnecting BOTH batteries then touch the positive and negative cables together to drain any residual power which may reset the memory. This worked on my Ex when my remote start/alarm system would lock all the doors each and every time I opened and closed a door.
