Default Prius key replacement

A heads up to all Prius owners: be extra careful not to lose your key. When I returned from a by-air trip, I discovered I'd lost my key. I called Toyota for a replacement and discovered it costs $191 plus tax and a charge for programming, which was quoted at $98!!! So, I'm not ordering it unless I and lose my remaining key. I'm writing to Toyota HQ to complain about the cost and the lack of notice of this cost. I understand it's due to the computer and anti-theft programming.

Goodness! Don't wait until you lose the second one. If you lose both, I hear it's a nightmare, AND way more expensive. They have to reprogram the CAR, not just the keys.

When we replaced our key, I tried programming it myself, but was unsuccessful. Had to go back and pay them the $50.

When I got my Prius, the Toyota dealer gave me a code number and told me to keep it in case a new smart key has to be made.

Lose both "smart keys and cost is slightly over $1,000 as new computer come with replacement. The coded numbers will get you the little metal key that slides into the "box" If you have one smart key remaining cost is slightly over a hundred to get an additional "smart key." (Thats my dealers story)

Absolutely do not wait another week even...you must replace the entire SKS ECU if lose both smart keys..one is required to reprogram the ECU. This is definately not a cost your warranty would cover. Some people have gone so far as to get a 3rd key just for the added security should both be lost.

The metal keytag that comes with your keys at purchase is the key cut code for the metal key. If you loose the last metal key, a new key can be cut from the keycode on the metal tag without the need to copy a physical key. HOWEVER, this tag code has nothing to do with the engine immobilizer security code! The metal code on the keytag will only get you a key to open the door, but not start your car.

The Prius has an engine immobilizer, so it must recognize a transponder chip in the key as one it knows about before it'll let you start your car. To program a new key into the car's security ECU (one of the computers), you first need a recognized master transponder chipped key. (For a Classic Prius, this is usually a black master key (NOT the grey valet/subkey). For the 2004+ Prius, any keyfob is a master if it starts your car.) DO NOT LOOSE YOUR LAST MASTER KEY! The security ECU cannot start the registration process for a new key without an already existing recognized key. If you loose all keys, you'll have to replace the security ECU with a fresh one, about US$1000. (a few years ago I weighed my Classic Prius' black master key, and figured using the spot price of gold for that day what the black key would be worth if it was made of gold. The replacement cost of the ECU is more than the price of that key made of pure gold, so that last key is literally worth its weight in gold!)

For a Classic Prius, you can purchase the keys online (like eBay), or here for $18+shipping: http://www.coastaletech.com/carkeys.htm You can have the metal key cut at any locksmith/hardware store.
You can program a Classic Prius yourself, although it may take a few tries to get the timing right: http://www.coastaletech.com/keys.htm
You can have 4 master keys and 2 sub keys.
(A master key is one that can start the reprogramming process of a new key. A sub key is allowed to start the car (disable the engine immobilizer), but it cannot make a new key. The grey key that comes with delivery is usually a sub key, and also has a different metal keycut to make it a valet key (cannot open the trunk).)

For a 2004+ Prius, note that there are two types of keyfobs available, a silver Toyota logo for a Prius with SE&SS/SKS, and a black Toyota logo one for a regular non-SE&SS/SKS equipped Prius. I'll note that on page 18 of my 2004 owner's manual it plainly states:
"Your Toyota dealer will need
one of them to make a new key with
a built.in transponder chip."
Shop around for pricing for the correct keyfob, discounts can be found at different dealers.
Although there are programming instructions around for doing it yourself, the instructions came from a German manual and may only work in that country (hasn't worked on a US Prius yet...) You will have to go to your dealer and have them program it for you using their special tester that talks with the computer. Be aware that you'll probably need to take all existing keys in to have them all recorded with the car's computer. Again, shop around for a dealer that has a lower per-hour labor charge, and one that has done this before (so it doesn't take forever while they learn the timing with your vehicle), as they have to program not only the car to recognize the keyfob, but also program the remote entry buttons (and also the SE&SS/SKS if so equipped).
Again, you can have the metal key cut at any locksmith/hardware store, for probably less than the dealer...

note that that is just the parts pricing. (yes, the metal key in the 2004+ keyfob is a separate part from the rest of the keyfob...) You still will have to pay a dealer for the programming labor.

Got a question for you.

I bought a fob. I paid for the programming.

I gave them the new fob and one of my original fobs.

They said they programed it.

The new fob will turn the car on and I can drive.

The new fob will NOT lock or unlock the doors. I have to unlock the door with the little key.

Is this right? All that money and the buttons don't work? I thought I read that I can have up to five master keys. I assumed that if I bought a third fob and I paid to have it programmed that it would work exactly like the first two and I would be able to use the buttons to lock and unlock the car. It seems stupid that a third driver would have to use his key to manually unlock the door.

Did my dealership's service department rip me off or are they just inept?

Just take it back and explain to them that the remote door lock feature doesn't work. They should make it better. It could be a problem with the transmitter or battery in the fob or it could be they made a mistake programming it. In either case, they'll almost certainly make it better. Well, if you bought the key somewhere else, you might end up having to return it for exchange yourself if they say the transmitter is defective.

It sounds like they forgot to test their programming, but I suppose it's possible the fob got dropped afterward or had an almost dead battery as delivered. Welcome to the brave new world where the customer is the beta tester.

When you return, bring all your keys/fobs. There's a tiny chance they'll decide they want to erase everything and start over.
