No, the guy said he wasn’t sure without doing a diagnostic test which would run $125 to diagnose it. Which, if I have to bite the bullet it’s ok, but figured someone might know on here ---

Sir would you provide the link to the service bulletin? I couldn’t find it ☹ ---

The bulletin is for vehicles sold by Southeast Toyota dealers with the accessory keyless entry kit, those systems come with a key fob, a separate transmitter. Your keyless entry transmitters are in the key handle, you don’t have fobs. The wireless entry receiver is powered by the “dome” fuse, does your dome light work? ---

This is the bulletin but I don’t believe it applies to your vehicle; [MC-10116439-9999.pdf (nhtsa.gov)](https://static.nhtsa.gov/odi/tsbs/2016/MC-10116439-9999.pdf) The wireless door control receiver is located in the right side C-pillar area, P/N 89741-02150, MSRP $550.65. Toyota parts are very expensive, you might try looking for a used one, if that is what has failed. With the cost of diagnoses, parts and labor, I think you will get used to using the key to unlock the doors. ---
