how to disarm the security system
You can't .. only a dealer has the equipment to disable it and it's illegal for them to do it You will have to get it repaired
Try this: with key in hand lock the car, wait at least 30 seconds, then using the key unlock the drivers door, if that didn't reset it then try the same procedure with the passenger door. If both procedures failed try disconnecting a battery terminal, turn on the headlight switch and wait at least 15 seconds then turn off the headlight switch and reconnect the battery cable, then try the reset procedure. If that fails then it is time for a dealer, it is possible that the antithieft system is not reading the shut down signals due to a bad door switch or wiring problem. HTH
Its time to go to the dealer...
