Introduction

This guide provides steps for replacing the battery in a wireless radio frequency (RF) key fob remote for a car or home alarm system. Specifically, it covers the ICT RF-REM2-433 model key fob, which uses a replaceable CR2032 3V coin cell battery.

Replacing the battery can restore function if the key fob can no longer lock/unlock car doors or arm/disarm an alarm system. The process takes about 10-15 minutes and requires a new CR2032 battery and a Phillips #00 screwdriver.

    • Place the key fob so that the back panel is facing up.

    • Use the Phillips #00 screwdriver to remove three screws securing the battery compartment cover.

    • If there are no visible screws, the cover may be held in place by clips or a sliding mechanism.

    • Carefully open the compartment using a small tool if necessary.

    My key fob was very intermittentin working so I have removed the old battery 2.65 volts, cleaned all contacts, inserted à new battery, checked the output on the fob contact points 3 volts, reassembled the key fob and it does not work. I then took disassembled the fob and put the old battery in and the fob works. Additionally my second fob was also not working so I tried a new battery and nothing. I inserted the old battery from the 1st fob and the second fob also now works. Any suggestions?

    • Take note of the battery's orientation (positive terminal up) before removing it to ensure you insert the new battery correctly.

    • Insert the new battery into the battery compartment, making sure to align it with the correct polarity (+ and -).

    • Put the battery compartment cover back in place by tightening the three screws using a Phillips #00 screwdriver.

    • Press a button on the keyfob to ensure it's working properly with the new battery.

    • If the keyfob doesn't respond, double-check the battery orientation and try again.

Conclusion

If the correct battery type was used (and installed with the correct polarity in mind), the fob should now function. If the fob still does not function, the circuit board may be broken.

To reassemble your device, follow these instructions in reverse order.

NOTE:

Remember to dispose of the old battery properly according to local regulations. If you encounter any difficulties or if the keyfob doesn't function correctly after replacing the battery, it's recommended to contact the manufacturer or seek professional assistance.

Thank you! You just made my day. I'm an 89 year old guy that needs some help sometimes. These fobs that they supply us for our underground parking garage in our retirement community don't seem to function very well. Thought I'd try changing batteries. Wish i could find a more powerful remote that would function with this system. We sometimes wonder if we are going to get in or out. They have had the overhead gate serviced a couple of times but it doesn't seem to help. thanks again, Arnie

Well, I'm not 89 but I still found this helpful. Wasn't sure how to pull the battery out without damaging the little clamp that was holding it in place so the tip to pry it out, gently pushing from under it, was very helpful. Thank you!
