2022 Toyota Venza Smart Key Replacement - Fast, Affordable & Professional

I was working out of Old Town National City on a Tuesday when a call came in about a 2022 Venza that was playing games with its owner. She said the push-to-start was responding maybe half the time.

Some mornings it was fine. By the afternoon she was standing outside pressing the start button through the brake pedal with nothing happening, then trying again two minutes later and it would fire right up.

She had already been to a shop. Not a dealer, just a locksmith someone recommended. They had programmed a replacement fob, charged her for the job, and told her she was good. That was about three weeks before she called me.

The intermittent nature of it was the tell. A cleanly programmed key either works or it does not. When it works sometimes and fails other times, especially in a pattern tied to temperature or how long the car has been sitting, you are usually looking at a marginal battery or a fob that passed initial registration but is not holding up through the deeper verification cycles the immobilizer runs after the first few starts.

I pulled up to her spot off a side street near the plaza in Old Town National City. She handed me the fob and I noticed it had some heft to it, which usually means the original cell. Cracked it open and sure enough, it had the factory CR2450 in it. Not the one the previous locksmith installed. I checked the contacts, seated a fresh cell, and tested touch unlock on both handles and the push-to-start response. Then I confirmed the programming through the diagnostic port to make sure the fob's registration was clean and not partially written.

It was the combination. The battery was marginal and the previous programming job had left the fob in an uncertain state. A full re-registration with a fresh CR2450 seated correctly and she was back to normal.

She mentioned the dealer wanted her to come in, leave the car, and wait for a diagnosis slot. She would have lost the car for at least a day. I was there and done in under an hour, right where she was parked.
