Replace the "lock" relay, found behind the fuse box. You have to stick your head where the gas pedal is, and look at the top end of the back of the fuse panel. There are 2 small square plastic boxes. Unplug them, spray them with electrical cleaning spray, and switch their spots. If everything works, there was some contact problem, if door will now lock but not unlock, one of the relays is bad. Part number "HMC DECO 95225 - 38300".

1998 Australian Hyundai Sonata GLE Classique key fob will not turn off immobilizer. Have replaced batteries. Can a new remote be coded/programmed or will I have to buy a new ecu. Please help.

You will not have to buy a new ECU. Key fobs are programmable. Try inserting the key in the drivers door and lock/unlock to see if security resets. Also try disconnecting battery and reconnecting

Hyundai 2002 sonata,,,, car has power locks.

You are correct in your assumption about a relay... there are two relays. One is for 'LOCKING' the other is for 'UN-LOCKING.' They are both labeled as "LOCK" relays (1 & 2). You can verify if a relay is bad by swapping one with the other. If the problem moves to 'unlocking' the doors, but will NOW LOCK - the relay is bad. If not, further troubleshooting is necessary.

Car will not start

replace the battery in the key fob and unlock the car with that, if u last locked the car with the key fob, you armed the alarm and can only be disabled by unlocking with the key fob, the car wont start because its an anti theft feature.
