I have a 2020 toyota tacome fleet that was used for fleet business.Its a 2.7 4 cyl 2wd .
It has several power options including locks an immobiliser feature.It also has a second obd2 pirt that had a tracker plug in in it.Company likely used it to track. .I was given a key with the chip in it no fob .I want to know how difficult it would be to install a key w the button fob to unlock the doors or a seperate lock unlock device.I see they come in lockb kits an some with push button start option which would be nice but I prmarily want a lock fob..I have a scanner with that key immobiliser set up~ ..ancel60000..Also ,is it possible to program these keys ,or do I not have the set up to receive tge signals ( didn't come w key fab nor made with it-base) But key has H on it .

Pic is key id like to get to work with it..or the fob...last pic my key.
I know the new kits have a key with them though .
Any information an suggestion is appeciated

Since your truck already has a transponder key that starts the engine, the immobilizer system is already working correctly. Was your Tacoma was originally equipped with the factory Remote Keyless Entry receiver? You might have power door locks but were not built with the factory remote receiver. If so, simply buying a factory style key with lock/unlock buttons will not make the buttons work, even if the transponder can be programmed to start the truck. Do you have power door locks that work from the driver's door switch, or are the locks manual only? Please let me know

A fleet truck made in mexicob with base model stuff but its rediculous to put all these other high end features on a 2020 tacoma with a 1970s key only entry ..even my 98 camary has buttons to get in an alarm..I do see lock kits sold online ..Can a dealer update software or do a flash, so the computer the locksmith uses to sync the button key will respond ?

The immobilizer and remote keyless-entry functions are separate, it can recognize the transponder in the H key for starting while still lacking some portion of the factory wireless door lock system. Don't bother with push-button-start conversion. Have Toyota or someone with proper Techstream capability run the VIN and check the truck's original option/build configuration, then look at the Body Certification Keyless-related ECU data to see whether wireless door-lock registration is supported. It might not be.

I asked the parts worker at toyota when getting a pcv valve an by the vin he said from what he found, it didn't come w the package features.
Does that mean no matter what program is in my tacoma originally that a dealer flash or any updates cannot be received ..?
An what about those kits online that work w electric door locks ?( I see a few say - made for Newer tacomas that must open door manually by key) ..thanks

Yep, your truck doesn't not have the feature you are looking for. I would look into the product in your link which will be the best way.
