2018 Toyota Highlander
Key Replacement - Save vs Dealer in San Diego

2018 Toyota Highlander Smart Key Replacement - Fast, Affordable & Professional

A woman in the Rancho San Diego neighborhood of El Cajon called on a Tuesday morning. She had one working key for her 2018 Highlander and had been meaning to get a spare cut for months. Then the one key started acting up, range dropped, the touch sensor on the driver door got inconsistent, and the push-button start threw a key-not-detected warning twice in one week. Now it was not a someday errand anymore.

She asked about the dealer first. They told her a few days out for an appointment, parts on order, and a number that made her pause. She found me instead.

I pulled into her lot off Jamul Drive with everything I needed already in the van. The fob battery was the first thing I checked. The CR1632 inside was not dead but it was reading low, which on this system is enough to cause exactly what she described. I seated a fresh cell, cleaned the contacts, and retested range at the car before touching anything else.

Range came back. Touch unlock on both front handles came back. The push-button start read the fob cleanly on the first press.

Then I programmed a second key so she had a real spare, not just a backup plan that might fail her in a parking lot. The immobilizer enrolled both fobs without issue. I cut the emergency blade inserts for each so she could get into the car mechanically if a battery ever dies completely again.

She stood next to the car the whole time, watched the whole thing happen in her own parking lot, and left with two working keys before lunch. The dealer comparison came up once, briefly. She just shook her head and said she wished she had called sooner.
