New Owner have a question about new key programming - Toyota Yaris Forums

BR4ND0N8 · 02-28-2024, 11:21 AM

I am having the same exact issue as you... did you ever figure this out?

2008 Toyota Yaris Base Sedan
power locks
chipless key
steel key
NO FACTORY KEYLESS ENTRY (NO KEY FOBS, NO [RECEIVER, DOOR CONTROL] MODULE)

I went to the junk yard and purchased a [RECEIVER, DOOR CONTROL] module from a 2009 Toyota Yaris Base Sedan.
Module info... RECEIVER, DOOR CONTROL - 89741-52170 - FCC ID: MOZB21RG

Purchased 2 MOZB41TG key/fob combination keys from Amazon that match what it says in the factory manuals for both the 2008 and 2009.

Connected the module.
Entered programming mode... works as expected.
Both MOZB41TG key/fob combination keys are recognized during the programming mode.
Open the driver door. (to exit programming mode)
Try the MOZB41TG key/fob combination keys... nothing happens.

I work as a Systems Administrator for a Toyota Dealership and I have asked a couple of my mechanic friends and they are stumped.

I have tried a different MOZB41TG key/fob combination key (Toyota OEM) from another vehicle and the same thing happens... appears to program during the process (lock unlock acknowledgement, etc.) but then nothing when attempting to use it.

I have also tried another [RECEIVER, DOOR CONTROL] module from a 2007 Scion tC Coupe.
Module info... RECEIVER, DOOR CONTROL - 89741-21040 - FCC ID: MOZB21RG
The process and outcome are exactly the same... appears to program during the process (lock unlock acknowledgement, etc.) but then nothing when attempting to use it.

Is there anyone that can provide any further recommendations?
