Experiencing a dead key fob battery can be more than just an inconvenience, especially when you’re miles away from civilization. One 2022 Toyota Tundra owner found this out firsthand during a camping trip, highlighting the importance of preventative measures for your vehicle’s key fob.
The Silent Key Fob Battery Failure
Imagine this: you’re enjoying a week-long camping adventure, and on the third night, your 2022 Toyota Tundra key fob suddenly stops working. No response when trying to lock the doors remotely. Initially dismissed as a fluke, the issue escalated the next night when the dreaded “key not detected” message flashed on the dashboard upon attempting to start the truck. Stranded at a state campground, miles from the nearest town, the realization of a dead key fob battery set in.

Luckily, after a night of cooler temperatures potentially affecting the battery, the truck surprisingly started the next morning. This allowed a desperate dash to the nearest store for a replacement CR2450 battery and a spare, just in case. This close call emphasizes a crucial lesson for all 2022 Toyota Tundra owners: be prepared for unexpected key fob battery failures.
CR2450 Battery: Your Tundra Key Fob’s Lifeline
The key fob for the 2022 Toyota Tundra relies on a CR2450 battery. It’s a readily available and inexpensive coin cell battery, but its failure can immobilize your vehicle’s remote functions and even starting capability. While modern vehicles are packed with sensors and warnings for almost everything, a low key fob battery indicator seems to be a surprising omission in the 2022 Tundra.

AJT Designs Fob Case and Battery Changes
For owners who have enhanced their key fob with an aftermarket case like AJT Designs, an extra layer of preparedness is needed. These robust cases often require a specific Allen key or wrench to open for battery replacement. In a pinch, the Tundra owner in our story was fortunate to have a bike tool with the necessary hex bit to access the battery compartment within their AJT Designs case. Without the correct tool, even a spare CR2450 battery would be useless.
Proactive Key Fob Battery Maintenance for Peace of Mind
The experience of this 2022 Toyota Tundra owner serves as a valuable reminder. Keep a spare CR2450 battery in your glove compartment or center console. If you use an AJT Designs or similar aftermarket case, ensure you also carry the appropriate tool for disassembly. While the battery life may seem short for a relatively new vehicle, especially with temperature fluctuations potentially playing a role, being proactive is key. Don’t wait for the “key not detected” message to leave you stranded. A small investment in a spare battery and tool can save you significant hassle and ensure you’re never caught off guard by a dead 2022 Toyota Tundra Key Fob Battery.
