I bought a 2005 sienna and bought 2 keys with transponders. they only cost 6.00 ea. do you think that they are with transponders? I can find on the website how to program a fob, but not a key. any help?

If it is for real, you got the steal of the year. Genuine Toyota D4 chipped transponder keys typically go for $30-$40, plus cutting and programming. Chipped keys have a 2 (?)
mm hole drilled up near the pastic handle that holds the coded device.

My toyota key (original) has a hole. the aftermarket key (not toyota) also has one. I got the FOB remote programmed OK, but I need the instructions to program the Key.

I found this some time ago on another forum. Try at your own risk!

Hi I have a 2006 Sienna. I bought a replacement 4D replacement transponder key on ebay ~12$. Had it cut at locksmith for 3$. I finallly found some instructions that worked for me and I know they also work for year 2009 (assume it would work for 07/08 as well but not sure). See Below

1. Open drivers door. All other doors closed but unlocked.
2. Insert the master key into the ignition and remove (without turning) 5 times leaving the key in the ignition on the 5th time.
3. Close and open the drivers side door 6 times leaving the door open on the sixth time.
4. The security light should illuminate solid red on the dash and stay lit. (This is how u know u are in program mode)
5. Remove the master key and immediately insert the newly purchased unprogramed key (do no turn)
6. Leave key in ignition for approx 60-80 seconds( security light will blink during this process). The security light will stop blinking. After the light stops blinking remove the new key.
7. Immediately insert the (old) master key and turn key to ON position then turn off and remove key.


You are done! Try new key and enjoy the fact that you outsmarted the dealer. Good luck:)

I will try it. I had some other instructions that open and close the door push on the gas and brake pedal 5 times and more. I have done it on my Ford and Chev. and it is simple. with all the closing of the doors etc, I thought it was a joke!!!!! I will let you know. ------

sorry it did not work. I did some more research on the website and used this one. the only difference is that you have to turn the NEW key to the ON position. IT WORKED ON 2 NEW KEYS

1) Buy a new transponder 4D-67 key ( $8.00+free shipping )from Ebay and Have it cut by your local locksmith($10.00).
2) Sit in your car with all doors closed.
3) Insert your original master key to key cylinder 5 times and leave it there.
4) Open and close driver side door 6 times
5)Remove master key from key cylinder, insert your new cut transponder key.
6)Turn that new key to "ON" position.
7)Then you look at that red engine immobilizer light , It is blinking..let's wait about 1 min and it will turn off by itself.
8)After engine immobilizer light turns off, Remove new key and insert original master key , Start engine , Engine starts, Great!
9) Now try your DIYed new transponder key to start your sienna.

Though about something - what would be the modified instructions for doing both new keys? Can you just insert them in sequence once you enter program mode and do them both at the same time, or do you have to start all over again?

I started all over again on the second key. I was just happy to get this process to work! It was the 3rd different process that I tried. I only paid 6 dollars each for the keys and I was thinking that the transponder was not in the keys. We really like the sienna, had 7 people in it last weekend and everyone was impressed with the room and the ride.

I them through amazon ---[FONT=Arial, sans-serif]Your Keyless Remote is the company. got the remote for 29.00. Their products are good, but they give NO support. They just say go to a professional!!!! If I was going to a pro, I would get the key from the same place--[/FONT]

Wow, that's good info. Can the mods make this a sticky?
Sure, why not? Good idea

I also took the liberty to change the title from "setting" to "Programming" a new transponder key.

I can confirm that process (from comment 4) worked for my 2005 Sienna LE. I did not have to turn the new key to on - just do the in-out with the master key and open-close with the door, then when the master key is removed the red key security light stays on, then insert new key to program (key security light changes to normal blinking) and wait 1-2 minutes until blinking key security light goes out.

Thanks!

Hi,

I have a 2006 Sienna XLE Limited and only one master key left. I purchased and cut two ebay purchased keys (keys, ~$8/ea and cut at Ace hardware, ~$3/ea) to work using a similar method. I've outlined it here and I've included a link to a youtube video that helped tremendously:

Here's what I did:
1) Start process with all doors closed
2) Insert existing master key 5 times, leave key it in on the 5th time
3) Next, open driver's side door 6 times, leave door closed on 6th time
4) Remove master key, security light should be solidly on (not blinking). You are now in programming mode.
5) Insert newly cut generic transponder key, leave in ignition until security light goes out (for ~ 60-90 seconds)
6) Remove key and start engine with master key, leave on for 20-30 seconds. Turn off engine and remove master key
7) Now insert newly programmed key, check to see if security light goes off, then start engine. Voila!, it should work.
8) You can't insert another key immediately afterwards (I was able to do this with my 2000 Avalon keys, but not with the 06 Sienna) to program it. You have to start the process over again, from the beginning, with any remaining keys you want to program.

Here's a link to the video that confirmed the process/helped me (it's for a 2004 Sienna, but it's the same process):

Hope this helps somebody out too and contradicts other posts out there (Lots I read via Google) that this can't be a DIY project.

I just recently purchased an uncut 4D-67 chipped key on Amazon along with a simple (no power door remote) for my daughter. Programming the key turned out to be remarkably easy, but I'm still struggling with the remote. That's another story for another day...

I muffed the key programming instructions and skipped some steps towards the end, yet found that it didn't really matter - the key works just fine!

What I actually did:

Purchased an uncut new transponder 4D-67 key on Amazon and had it cut locally at a hardware store.
1) Sat in the van with all doors closed but unlocked.
2) Inserted the original master key into the key cylinder (in and out) 5 times and left it there.
3) Opened and closed driver side door 6 times.
4) Removed master key from key cylinder, inserted the new key.
5) Turn that new key to "ON" position (but not “start”).
6) The red engine immobilizer/security light blinked for a little over a minute, and then went out.
7) Now here is where I messed up – according to all of the other programming instructions you are supposed to swap back to the master key and start the engine, then turn it off and start the engine with the new key.

I simply started the van with the new key when the light went out in step #6, and it worked!

I bought a transponder key for $20 on Amazon (Urban Inspirations). I tried the three different programming methods on SiennaChat and none of them worked. The security light never went off except when my real Toyota key was held next to the ignition. The seller just said the get it programmed at my Toyota dealer. I went there and was told it would cost $60 to try programming it and third party keys work less than half the time. A new key is $40 at the dealership. It seems dumb to risk wasting $80 for half a chance at saving $20. Maybe the odds are better for later model Siennas.

This is the correct programing procedure, or atleast it worked on my vehicle. The dealership ( stealership) wanted $75.00 to do this and said it wouldnt work.
