Hello. Security systems (alarms) can cause problems when they become bad. The best thing to do is disconnect the fuse for the alarm. Look in the fuse panel of your car and see which one is for the security system (alarm). Then you can pull out the fuse and it will disarm the security system. Good Luck.

This is very possible, and it can be done yourself. Go to this link. Read thru it in entirety so you understand how the system works. There are some links on there that will help you out.

If you are handy with vehicle electrical, you can apply ground to the factory disarm wire, to permanently disarm the factory security. It's location and color;

Factory Disarm Purple/Yellow (-) in Driver's Kick Panel---Black Connector

Sounds like it a security system problem. It could have disabled the car from starting. If it is a security issue, it will have to be taken to a dealer to bypass it or fix the issue. Not sure what type of system is on the car, but if it's factory, then look through the manual under (alarm) or (security) it should explain how to disarm the system. All cars are different so it's hard to tell you the exact disarm method.

Try turning the key in the rear hatch key cylinder. That should disarm the factory security system.

the system is disarmed every time you lock and unlock the doors with the key or remote, there is no other disarm, so if that is not happening the system has a fault and will need to be scanned for the problem part

was it a professional or shade tree install? the following is off vipers website:
disarming without a remote control
This feature allows you to disarm the security system without the
Remote Control should it be lost, damaged, or disabled. In order to
disarm the system without a remote remote control, you must have
the vehicle’s ignition key and know where the Valet button is
located. Be sure to check with the installer for the location and the
number of presses of the Valet button required to disarm the system.
To disarm the security system,
turn the ignition to the ON position.
Press the Valet button the
preset number of times (one to
five times) within 15 seconds. After five seconds the system will
disarm. If the system does not disarm, you may have waited too long;
turn the ignition off and on and try again.
if that doesn't work try this other

valet mode
You can prevent your security system from automatically arming
and triggering by using Valet Mode. This is very useful when
washing the vehicle or having it serviced. In Valet Mode, the
security system will not arm, even with the Remote Control, but
all convenience functions (door locks, trunk release, etc.) will
continue to work normally.
To enter or exit Valet Mode:
1. Turn the ignition on.
2. Turn the ignition off.
3. Press and release the Valet
button within 10 seconds.
The status LED will light solidly if you are entering Valet Mode,
and it will go out if you are exiting Valet Mode.
