Key Detected without fob present

2023 TRD that I bought used, started giving a key detected warning when I tried locking it. This recently started after I had installed a Redarc liberty trailer brake controller. To my knowledge I was only ever given one key fob and the truck has worked great for over a year. This is a recent development. Any advice on this would be appreciated as I was able to start the truck and drive it around with the keys on the kitchen counter

 

Always start with what was last touched

I'd disconnect the controller and see what happens

 

Welcome! You stated that this all started after the brake controller installation. Can you reverse the installation to see if that corrects it?

 

Apologies, I forgot about a spare key that was given to me when I bought the vehicle. I recently moved and all my stuff was packed in the vehicle.

 

That's a good one!

 

Mystery solved! You'll fit right in here OP.

 

Welcome to the forum

Glad you solved the "problem"

 

Thank you for letting us know the solution.

So many ask things and never come back with results.

 

That was like a $300 fix for the dealership.

 

^^^Without finding the problem. Fixing it costs extra.

 

Wheeew 4:20

 

Op be careful with that red arc, I had one, it was a vampire.

 

Welcome from Denver!

 

Good outcome and "resolution".
