Are you experiencing unexpected battery drain in your car key fob? It’s a common issue with modern vehicles that use radio frequency (RF) key fobs. If you keep your key fob too close to your vehicle, especially while at home or camping, the constant communication between the fob and car can lead to unnecessary battery depletion. This isn’t specific to any car brand but affects many vehicles with keyless entry systems.
To combat this key fob battery drain, you have a couple of straightforward options. One method is manually disabling your key fob’s signal by pressing and holding the lock button while quickly double-tapping the unlock button. However, remembering to do this consistently can be tricky, and accidentally pressing a button could reactivate the signal. A more reliable and hassle-free solution is using a faraday bag for your key fob.
A faraday bag, sometimes called a faraday pouch or box, is designed to block electromagnetic fields, including the RF signals emitted by your key fob. Skeptical at first, we tested a few faraday bags for key fobs purchased online. We found a set on Amazon that were perfectly sized for key fobs and incredibly effective. Once you place your key fob inside the faraday bag, the car no longer detects its signal. It’s a simple and incredibly effective way to prevent battery drain. Plus, these bags are very affordable – we got a two-pack for under $10!
If you’re looking for an easy and cheap way to prevent your key fob battery from draining unnecessarily, consider a Faraday Bag For Key Fob. It’s a small investment that can save you from the frustration of a dead key fob battery and potential vehicle battery issues in the long run. You can find similar faraday bags online, like the ones we tested from Amazon, by searching for “faraday bag key fob”.
