2012 Acura MDX Remote Flip Key Replacement - Fast, Affordable & Professional

The dog was in the back seat. August. Car off, windows cracked a couple inches, AC not running. She had just finished a vet appointment near Bay Marina and the fob quit on her in the parking lot. Pressed the lock button, nothing. Pressed unlock, nothing. She could see the dog through the glass.

She called the dealer first. They told her the earliest appointment was the following afternoon.

Then she called me. I was twenty minutes away.

First thing I did when I got there was get the door open with the mechanical blade so she could pull the dog out and get him into the shade. That part comes before anything else.

Then I started looking at the fob. This is a four-button remote flip key on the 2012 MDX, and when I popped the housing I found the CR1616 cell had corroded inside. The kind of corrosion that does not just kill the battery, it damages the contact and can foul the board. The housing itself was worn enough that moisture had found its way in over time. The fob was done.

I replaced the whole unit, programmed it through the OBD port, and went through every button before I handed it back. Locks, unlock, trunk release, panic. Then I watched her start the car and let it run for a minute.

Start to finish, forty-four minutes from her phone call to the engine running. The dealer wanted her to sit in that parking lot with her dog until the next afternoon. She paid a fraction of what the dealer quoted.

The dog was fine.
