2015 Acura RDX Smart Key Replacement - Fast, Affordable & Professional

I got a call one Sunday morning from a server who works a brunch spot near Ramona Highlands. She'd already been through it once with another locksmith, and she was not happy to be calling again.

The situation: she had a 2015 Acura RDX with a newly cut and supposedly programmed smart key. Car would crank fine, run for about two seconds, then die. Every time. The previous tech told her it was a module problem and moved on. She paid him anyway.

It was not a module problem.

What happened is something I've seen before. Acura's immobilizer registration has a timed sequence built into it. If the process gets rushed or a step drops out, the system accepts the key data in a temporary buffer but never commits it to permanent memory. The car fires up because it recognizes something, then the security system catches the incomplete registration and kills fuel delivery. Two-second stall. Every time.

I verified the mechanical cut first to rule that out. Then I connected through the OBD port, cleared the incomplete key data from the previous attempt, and ran a clean immobilizer learn from scratch with the correct timing. When it finished, I confirmed the fob registration was written permanently, not just sitting in a buffer. Then I walked every function: door handle touch unlock on both sides, lock, unlock, the hatch release, start. She watched the confirmation on my screen. I showed her specifically what "fully learned" looks like versus what the previous attempt left behind.

Car started clean. No two-second cutoff. No hesitation.

She'd already paid someone else for a job that wasn't done. I couldn't fix that part. But I could make sure she left with a key that actually worked, done right the first time out here in Ramona.
