Key Fob Not working or programming (FIXED) - Toyota 4Runner Forum

YotaKyle · 07-22-2019, 08:53 AM

This is for anyone else that may be chasing a rabbit like I was here recently. My Key Fobs suddenly stopped working one day and I tried everything.Reprogramming, tested batteries in the Fob, check fuses I assumed were associated with the Key fob or doors locking/unlocking. Come to find out, of all things, it was a blown fuse in the "Dome Light" slot under the hood. Replaced with a 10A fuse and suddenly the key fob debacle was solved.

This may already be known by most but as a new owner of a 4th gen and in case someone is in my shoes again, I hope they find this.

I had the same problem when I bought my 4Runner. Fuse kept blowing, taking out the door lock, clock, trip odometer, and interior lighting.

The step lighting is also on that circuit. It turns out I had a shorted wire at one of the sockets. Make sure that if you're having a repeated fuse blowout, that you're not experiencing a short somewhere. Don't just throw in higher amp fuses.

My issue was due to deleting the step rails and their lighting. I put in the same fuse that the the Dome light fuse called for.

I checked the dome light fuse and the security fuse. Both had not been blown. I tried my key fob again and it started working. This was an easy fix.
