IMMO Coil Tester

The Auto Lock inspection loop is essential for a locksmith or key programmer.

Checking the auto-lock loop:

• if the light is on, the loop has no problem;
• if no light is on, it means the lock loop has a problem.
• if the light is on but the car won't start, it means the chip has a problem.

How to use:

• Put the tester to the ignition (as in the picture below);
• Put the key in the ignition;
• Start the vehicle and observe the signals from the diode.
