Portable Car Lock Alarm: warning LED, strobe light and a 120db alarm

The patented design of the SWAT LOCK not only protects your car with an ear piercing siren but also locks the steering wheel in place to prevent potential car thieves from turning the wheel.  It is equipped with four theft-deterrent features: warning LED, flashing strobe light, 120 db siren and a hard steel lock. This alarm simply locks on to the steering wheel in less than 10 seconds - no wires to run or expensive installation is needed. Three keys are included for unlocking the alarm. You can set your own remote control code.  The alarm will sound and LED will flash for a 30 second cycle when disturbed by window tapping or other significant jolt and will reset if there is no other disturbance.  If the disturbance continues the alarm will continue for another 30 seconds until the disturbance ends or the alarm unit is disarmed. The alarm unit requires two (2) 9V batteries that are not included.  The IR remote requires 1 12V battery that is included.  Dimensions: 14.5 inches by 7.75 This alarm has a 1 year warranty.
