Keyless Entry Tester - J-43241

This tester is easy to use and performs a simple pass/fail test on remote keyless entry transmitters.

When a keyless entry transmitter button is pushed and nothing happens, you have one of three possible concerns.

• The batteries are dead
• The transmitter is defective
• The receiver is defective

Once you have determined that the problem is not the batteries, the J-43241 Keyless Entry tester determines if it is the transmitter or receiver.
Works on virtually all GM automotive keyless remote transmitters
