Quick compatibility check
What battery does your key fob use now?
Install like a batteryDesigned as a drop-in power module for compatible CR2032 key-fob compartments.
Sleeps after stillnessThe fob is disconnected from power when the key is left alone.
Wakes when movedYou won't notice any difference. Motion restores power automatically.
May extend key battery lifeLong idle periods can reduce the energy used by the key fob itself. Actual battery life depends on the fob and how often the key moves.
Compatibility
Check your vehicle and key fob.
Choose a year, make, and model from the catalogue below. We show exact battery-size information where it is available and a cautious check-your-fob result where the remote style can vary.
A yellow result means either the listed fob uses CR2032 but remains untested with Lo-Key, or the battery varies by fob style and must be checked. A red result means the listed fob uses a different battery. Because key-fob styles can vary within the same year and model, always confirm the marking on the battery inside your key.
Not listed?
A CR2032 marking is a good starting point, but compartment clearance, contacts, and pulse-current requirements still need to be validated.

Safety & limitations
One layer of security - not a promise that a vehicle cannot be stolen.
Product Warning
Lo-Key is designed to reduce exposure to relay attacks by removing power from an idle key fob. It does not stop other theft methods that do not depend on the key’s wireless response.
Coin batteries can cause severe injury if swallowed. Keep the product and any removed battery away from children. Do not recharge, crush, puncture, short-circuit, disassemble, or expose it to fire or excessive heat.
Product FAQ
Before you add it to the key ring.
Yes, Lo-key will work on the spare key. Protecting the spare key is especially important since it may remain near the outside of a home for long periods without being noticed.
No. It is designed as a replaceable coin-battery module, not a rechargeable device. Service life will depend on the key fob’s current demand, and how often the key is active.
The functionality of the battery can be tested by locking the vehicle and placing the key on the ground beside the car, leaving it undisturbed for at least 3 minutes. The key will power off, and the vehicle's doors will not unlock when the handle is pulled. Keyless entry function can be restored by picking the key up.
