High Quality Ignition Key Immobilizer Transponder Antenna Tester EZS EIS Test Coil Automotive ECU Induction Signal Detector

An independent device that will light an LED to show any interaction between the ignition key and the ignition switch transponder antenna.

A simple, quick and cost effective method to eliminate a failure-to-start situation which can occur if;

An incorrect key is used.
The transponder antenna/system is defective.
The ignition key is faulty or requires recoding.

With any of the above faults an engine may well crank over but still fail to start.

can quickly move on to investigate other possible causes of failure such as ;
Fuel, No spark, Injectors.




Instructions:
Place the Tester over the ignition switch.
Introduce the ignition key through the hole and into the switch
In most applications when the key is turned to the ignition on position, the TEM1253 Led will flash once to signal that communication between the key and transponder antenna is correct.
On some vehicles, when the key is in close proximity to the ignition switch, the LED may flash bedfore the key is even turned. This is also an indication of good communication.
