New Key Fob couldn't be programmed

Ask for your money back.

Or, ask them to research a "seed reset". They will have to call Toyota and reset the immobilizer ECU. They basically need to treat the car as if all keys have been lost. It may cost you another $100, but it would allow you to have the smart aspects of both fobs programmed.

 

Not to contradict seilerts advice (he is wise, and may be 100% correct) - try to wait a bit for RobH to chime in, before spending more money. I think Rob has the knowledge to guide you appropriately, because there are definite differences between Gen2 & Gen3 fobs. Since you appear to have a Gen2 & new fob to boot, I think you can try 'chicken-dancing' your way through the two individual programming operations, rather than visiting the dealer for Techstream access.

Note: Gen3's on the other hand, require the seed re-set in the event of a 'no fob' or 'used-fob' situation. New fobs do not need the seed re-set, but do need Techstream to add one (so goes current thinking, since no one has tried to 'chicken-dance' a new fob, at least to date.)

It is the aspect of the original fob not having SKS functionality that confuses me. Starting from scratch makes the most sense. Nevertheless, it is disheartening that the dealer would charge so much, deliver nothing, and somehow think that the customer would be okay with it.

 

A few guesses in order of probability...

The KEY switch below the dash is set to disable SKS function. I don't remember which way is which, but reverse it and see if the smart function returns for the original key.

The battery in the original key is weak. Try replacing it.

The new key isn't new. Once a key has been registered with a car, a seed reset is required to register it with a different car. Some keyfobs are sold with a new (uncut) mechanical key, but that says nothing about the electronic part.

A 2007 with NAV is an SKS car. SKS keyfobs have a silver logo, while non-SKS keyfobs have a black logo. Unlikely, but the logo panel could be switched from a different type keyfob. It's not the logo that makes it SKS - it's the SKS electronics inside the keyfob.

There is a limit of 5 keyfobs that can be simultaniously registered. Since two keyfobs came with the car originally, there is a least one out there that still works with your car. Even ignoring the bad new key, I'd recommend the "erase all keys except the current one" function. Otherwise, a previous owner still has a key to your car.

Registering keys on a Gen2 is tricky. If the technician missed a timeout, the registration would fail. This is something that takes a lot of fiddling to make work. If the new key is truly new, then the DIY chicken dance should be adequate to register it.

There could be a failure in the car of the parts related to broadcasting data to the keyfob. The SKS system wouldn't work, but pressing the buttons would.

If the dealer can't register the new keyfob, then I think the seller owes you a refund and/or a replacement. This is a good reason to purchase a new keyfob from the same dealer as you have register it. If a technician trys one and it doesn't work, he just goes back to the parts department for another one to try. The one that didn't work probably ends up on eBay...

 

I never even thought that the *new* fob could be a *used* fob, and requiring the seed re-set - Doh!

And there you have it shoedad. I think seilerts and RobH have your situation about covered. There might be one other forum member (Tom) who might add something to everything given so far... wait for it ;-)

These three guys are my picks for credible SKS information.

Safe trips

 

The previous posts have this well covered. Since the original fob does not work with SKS, the dealer needs to do a seed reset and add both fobs to the system.

The old school mechanical key is a standard Toyota key blank that can be cut by any locksmith. The one in the fob has a funny head made to lock into the fob, but the key blade is standard. See if you can buy a blank fob key from a third party, then take it to a good locksmith to get it cut. Otherwise, just have your key duplicated on a standard Toyota key and keep it on your key ring.
