Makes a beep noise every 45 seconds, sounds like the same kind of beep the anti-theft device makes when you start the car

Make sure all the doors, Windows and trunk are closed and that no lights stay on inside. If a light does stay on inside the anti-theft may think it's an open door or someone is still inside. Also, if you have a lot of stuff on a seat, the pressure sensor in the seat may tell the anti theft there's still someone inside the car. You should usually get a confirmation of some kind that the anti-theft is active, unless the confirmation was turned off in the vehicle's settings.

Try pulling the fuse for the anti theft system and starting. If the car starts normally, then the problem is with the theft system. The theft system will reset itself after a period of time.

Anti-theft system can keep vehicle from starting , Alarm is for vehicle content theft , open door without key alarm sounds (horns) ! PATS - passive anti theft system PATS enables and disables the engine from starting ,it will not cause the engine to die ! You have some other kind of problem ! If the vehicle engine doesn't turn over an red light on top of dash flashes fast ,then you have anti-theft system problem !
PATS differs from the perimeter anti-theft system in that PATS enables and disables the engine from starting. If equipped, the perimeter anti-theft system protects the perimeter of the vehicle (doors, hood and trunk) and sounds an alarm.

Is the red light on the top center of the dash pad flashing fast when trying to start ? The engine doesn't turn over ?
Anti-theft system problem !
PATS uses a visual theft indicator. This indicator will prove out for three seconds when the ignition switch is turned to RUN or START under normal operation. If there is a PATS problem, this indicator will either flash rapidly or glow steadily when the ignition switch is turned to RUN or START. PATS also "blips" the theft indicator every two seconds at ignition OFF to act as a visual theft deterrent.
PATS differs from the perimeter anti-theft system in that PATS enables and disables the engine from starting. If equipped, the perimeter anti-theft system protects the perimeter of the vehicle (doors, hood and trunk) and sounds an alarm.
The PATS is not compatible with aftermarket remote start systems, which allow the vehicle to be started from outside the vehicle. These systems may reduce the vehicle security level, and also may cause no-start issues. Remote start systems must be removed before investigation of PATS-related No Start issues.

contact the manufacturer of the after market anti-theft system for advice. without knowing the make and model information, no one can help you further.

Hi Arkrios, It sounds to me as if the anti theft program of the alarm system has kicked in. I believe you'll need to get the system recoded. Regards John

if anti theft module not communication with scanner or diagnostic hook up then your vehicle will probably not start till thats corrected and clicking sounds like relay from security system opening up and shutting down power for starting system
