How do I Reprogram the Keyless entry for my 2009 Toyota Prius?

first, you would have to determine if you have the correct key fob. once you do, search for 'chicken dance' and see if that will work for you. sometimes it does, and sometimes it doesn't.

alternatively, search around for a locksmith who can do it.

all the best!

 

If the spare fob never worked, it is unlikely that you will get it to work by doing the chicken dance. Would be nice but I wouldn't bet on it.

The dealer can program it.
A locksmith can program it.
You can buy $100 of equipment and program it. (Plus a few hours of your time setting everything up.)

In the meantime, you can go to a keymaking place and they can make a copy of the physical key onto a normal key blank so you don't have to use the tiny physical key that Toyota provides.

Eventually you'll want to get extra fobs.
And it is better to program them all at once.

Are you in the Madison area?

 

Sorry, I've only just seen this one (…shouts of "…so what's new?"), but have you checked the 12V AuxBattery? (…I had a similar problem about 3 years ago, and that fixed the problem (…as may be discovered in threads passim) - hope this helps - Wil - Good luck!
PS: look at @bisco 's sig.

 

Any fob needs to be paired to the car. Since you don't have a fully working fob, you will need someone with the software to force the car to recognize the fob. If you had a working fob, then it is possible to do the chicken dance with the new and old fob to get the new fob working.

Used fobs can be paired to the car. However, I think that requires the software.

I suggest: Get a new fob from a dealer, or a locksmith that knows what they are doing. Make sure you get them to fully reset the car so that you can easily add additional fobs later (max of 5 fobs per car, so while they are at it, you might as well have them fully clear the car).

Then, you can buy a new fob off ebay from a dealer for $150. With the newly programmed fob, you can program additional NEW fobs using the chicken dance.

FYI: pay $10 to have a dealership cut the key. I had a local locksmith ruin the key when he tried to cut it.

 

A lock smith or dealer can add a New fob to the car, esp if there exists a 100% functional fob.

When you loose all working fobs, or have incorrect fobs like poster #1 (those fobs were never for his vehicle), or you want to add used fobs to work 100% correctly, you will have to seek dealer help. Few locksmiths pay for the vehicle security licensing that allows them to do a RESET (clear all authorized fobs) and RESEED (add new and used fobs to work 100% correctly).

If one has to go to the dealer for the RESET/RESEED procedure, it is best to get new (100% virgin fobs) b/c of the labor cost at the dealer. Also, the price difference between used fobs (found on the street and now being sold by someone on fleaBay) and 100% new fobs has shrunk considerably. Just not worth it given the small price difference, esp when facing a few hundred dollars in dealer labor.

 

Since you have 1 fully working key you can do the chicken dance using your fully working key to program the new key. Somewhere in the thread people started assuming you didn’t have a fully working key. I read your posts as you do.

 

Here's your invitation to the chicken dance: How to Program a New Key Fob for Full SKS Functionality | PriusChat

Along with a working original SKS FOB, I bought a new SKS FOB off amazon and this method worked for me.

 

So do you or don’t you have one fob that works completely? I can’t tell from this post.

 

Yes the FOB's have a battery. You'll need a small screwdriver to access it. Search youtube for replacement video.

The new FOB can't be a used unit/seeded with another car and the car can only seed 5 FOB's total counting the original two.

 

SKS is smart key system. AKA keyless system that doesn't need to be inserted into the dash to start the car. The SKS fob can stay in your pocket, purse, etc. Is that what you have?

 

If you have SKS there is a button at the bottom of the dash under the steering wheel to turn it off. There are 2 distinct chicken dances one for SKS and one for non SKS. You need to know what one you have before you start.

 

You don’t even know if the fob has a battery? I suggest you read the owners manual before asking for any more advise.

 

I would add: read the owners manual in its ENTIRETY!!!
