2010 Mazda CX-9 Smart Key Replacement - Fast, Affordable & Professional
Over near Montecito Village Grocery, a shop foreman at the alignment place flagged me down about a customer's 2010 CX-9 that was completely dead to smart key commands. Another locksmith had attempted the job earlier that morning. The tool lost connection during the security countdown, and the keyless control module, Mazda part number GS1E-67-5RZ on these first-gen CX-9s, dropped into a hard fault state. No start, no remote lock, nothing. The customer was sitting in the waiting room watching the whole thing unravel.
When I got there the other tech was already gone. The car just sat with "KEY IS NOT ACCESSIBLE" stuck on the dash.
I hooked my jump pack to the battery first. Power stability during that timed security sequence is everything on these. One voltage dip and the module faults out, which is exactly what happened the first time around. I pulled codes through OBD, cleared the fault state on the keyless module, and started a clean programming cycle from scratch.
His fob was legit OEM, WAZX1T763SKE11A04, 4-button smart key, part number NHY8-67-5RYA. The module accepted the reset and the fob registered on the first clean pass. Tested push-button start, door touch sensors both sides, hatch release, lock and unlock range.
About an hour and fifteen minutes total, including the diagnostic cleanup the previous attempt left behind. A fraction of what the dealer route would have cost after the tow alone.
