Anti-theft light stays on still wont start

This question was already asked but did not work in my case

Question: 1993 Jeep Grand Cherokee V-8 mileage: 105,000. I disengaged the battery to check the water pump and after I hooked the battery back up, I noticed my alarm was "tweaking." I tried to take the Jeep to town, and it kept cutting out on me-which is the anti-theft part of the alarm, but how can I reset it to where I can drive the vehicle? I turned the valet switch off and then on, but nothing happened.

Answer: Try locking and unlocking the rear hatch. This should reset your security system.

So now what still cant get it started ...
Do you

Try this, found on the web:
This information applies to a Vehicle Theft Security System (VTSS) that was armed when the battery was disconnected and reconnected.

When the armed VTSS senses that the battery has been disconnected and reconnected, it enters its power-up mode. In the power-up mode the alarm system remains armed following a battery failure or disconnect. If the VTSS was armed prior to a battery disconnect or failure, the system will have to be actively or passively disarmed following a battery reconnection.

The power-up mode will also apply if the battery goes dead while the system is armed and battery jump-starting is attempted. The engine no-run feature will prevent the engine from starting until the alarm system has been actively or passively disarmed.

Passive disarming of the Vehicle Theft Security System (VTSS) occurs when the vehicle is unlocked using the key to unlock either front door or the lift gate. Active disarming of the VTSS occurs when the vehicle is unlocked by depressing the Unlock button of the Remote Keyless Entry (RKE) transmitter.

Once the alarm has been activated (horn sounding, lights flashing, and the engine no-run feature), either disarming method will deactivate the alarm.

Depressing the Panic button (if equipped) on the RKE transmitter will also disarm the VTSS, but the horn will sound and the lights will flash for about three minutes as part of the Panic feature. The horn and lights can be stopped by pressing any of the RKE transmitter's buttons or driving the vehicle above 15 mph.

Or being a 1993, if it's still too much trouble, you can disable the alarm system all together. I'm not going to give info publicly on that, because would be theives could use it. If you still need help on this, contact me via the private message system.
