AUTOOL RE110 Car Key Frequency Tester

AUTOOL RE110 Car Key Frequency Tester

The AUTOOL RE110 is a compact tool for checking whether a car remote key is actually transmitting. It measures and displays the key's frequency, tests infrared output and checks common key-fob batteries, so you can confirm the remote is working before diagnosing the vehicle.

Who It Suits

Locksmiths, auto electricians and workshops dealing with remote key and immobiliser issues, and anyone needing a quick check of a key fob.

Key Features

• Frequency detection for 315 / 433 / 868 / 902 MHz remote keys
• Wide use – door handle signals, immobiliser signals, garage keys and electronic doors within the frequency range
• Infrared test to check an infrared remote
• Button battery test for CR2025 / CR2032 key batteries (0–6V terminal voltage)
• 1.9-inch backlit display for clear readings
• Folding back bracket so it stands on the bench hands-free
• Two power options – Type-C (5V/1A) or 4 x 1.5V AAA batteries

Please Note

• The RE110 detects the frequency band of supported RF and infrared signals and shows coin cell voltage. It does not program, copy or pair keys.
• Type-C cable and AAA batteries are not included.

How to Use

• Hold the key close to the testing area and press a key button
• The frequency is displayed on the screen; testing closer gives a more accurate reading
• If no value displays, the key frequency may not suit the device
