Took the battery out to recharge it. The horn started blowing to stop it I put the key in the door and turned it. I replaced the battery and now the car wont start even click and the security light is blinking until I close the door. Someone suggested it might be the relay.I need the procedure to reset the anti-theft system.

If the remote doesn't reset the alarm. Then it sounds like you have a problem with system which has a service bulletin

Classification:
EL97-005
Reference:
ITB97-027
Date:
May 28, 1997
1996-97 I30 DOES NOT RESPOND TO REMOTE

APPLIED VEHICLE(S): 1996-97 I30 (CA32)
APPLIED VIN(S): Vehicles built before JNKCA21D*VT501507
APPLIED DATE(S): Vehicles built before August 1, 1996
SERVICE INFORMATION

This bulletin provides information to address the concerns of any 1996 or early 1997 I30 owner who states their vehicle does not always respond to the remote switches. This incident is a cycle where a customer cites an inoperative remote switch, the dealer reprograms the remotes and the incident returns for no apparent reason.

Troubleshooting the remote control system per the service manual reveals not problems with the remote batteries, antenna, LCU05, BCM or wire harness connections.

Such an incident may be caused by the owner jiggling the ignition key after locking the doors. The sequence of these events erases the remote ID codes from memory.

There is a countermeasure multi-remote control unit available (which prevents accidental remote ID code erasure) to resolve this incident.

SERVICE PROCEDURE

1. Interview the customer to see if they usually lock the door before starting the car.
2. Use the 1996 service manual page EL-220 to test the Multi-Remote Control System. Perform the six diagnostic tests for symptom: "All functions of remote control system do not function".
Figure 1

3. If the system checks out OK and the customer usually locks the doors before starting the car, replace the multi-remote control unit (LCUO5) in the trunk with the countermeasure unit as follows (see Figure 1,):
A. Remove the right side trunk finisher.
B. In the right wheel well area, replace the control unit.
C. Reinstall the trunk finisher.
D. Use the 1997 service manual page EL-257 to reprogram the remote(s).

Please let us know what happens.

Cheers, Ken
