Appreciate any advice—my Lexus GX SUV won’t recognize the key.

Just what I needed! My Lexus GX SUV has been acting up lately.

I can’t believe I found this. Been stuck with my Lexus GX SUV too.

My Lexus GX SUV is basically useless until I get this code. Fingers crossed.

Common questions about key programming, fob issues, and replacement options

Lost Keys
Dealerships can often cut keys using your VIN, but will require proof of ownership. This only works for original factory keys - aftermarket or previously replaced locks won't match. The key will still need programming to start the car if it has a transponder.
