Perhaps I missed it in this long thread, but what I found was that it is important to go through the various steps outlined at the beginning of this thread fairly quickly. I did the five "key in and out" routine quickly, then with no delay, I did the 6 "door open and close" routine right away.

When I did this slowly and deliberately, I could not get the security light to light continuously, indicating the vehicle is in programming mode. As soon as you put the new key in the ignition lock, the light will begin to blink. Wait about a minute to maybe two, and it will go out. At this point, the new key is ready to use.

I find it much easier to program transponder keys with Techstream and also the key fobs. None of that opening and closing the door x number of time or inserting and taking the key out of the ignition x number of time.

Transponder keys are programmed thru the immobilizer module and key fobs are programmed through the body control module. There is a maximum of 4 fobs that can be program into the car module so if you didn't get a second fob when you bought the minivan, you can only add two more fobs. You must clear all the fobs in the car computer if you want to add three additional fobs if you didn't get the second fob.

While I certainly agree with the comment about " opening and closing the door x number of times...", I can't justify getting yet more stuff I'll use hardly ever. If I was more into the workings of the electronic systems of my Sienna, it would be a different story.

This is a great forum and the instructions in this thread saved me a lot of money, and gave me some satisfaction. When I want to get serious about playing with cars, I work on my Mustang.

This procedure worked perfectly....I paid $12 for a real Toyota transponder key on ebay, had it cut at a shop for $6 and programmed it in my driveway for free....

Walmart wanted $60 for the key (programmed) and Toyota wanted $105.....thanks guys!!!!!!!!!!!

I've probably tried this a dozen times on my 2005 XLE I purchased used. The previous owner only had one key. Every time I go through the process, the light does not go solid (programming mode). I've watched the video and read every comment. Tried it fast, tried it slow. I've done the key in/out fast and also slow enough for the light to go out between. Nothing seems to work. Thoughts?

I think on the newer Toyota's (2014 - 2018), this older method of programming FOB's won't work. You need the dealer or a locksmith or get hold of TechStream software with cable to program them. Been running into this issue with my 2014 Camry.

Here's a couple options for programming keys and remotes for Siennas. Full disclosure - this is my YouTube channel and associated key programmer company. It's way too expensive to get a new fob / key / remote (whatever you like to call them) and get it programmed. So I decided to do something about it.

Programming Remote on 2nd generation Siennas (2004-2010)

Programming for newer Siennas (as well as 2nd generation)

Newer vehicles don't allow programming without electronics. I got frustrated with prices from dealership/locksmith and started a company to rent programming devices for Toyota Keys and Remotes. Here's a demonstration.

I'm also looking for Toyota owners interested in being part of a beta test for vehicles that I have not yet been able to test programming. If interested, contact me via email at mike <at> tomskey.com

My locksmith wasn't sure if his machine could properly cut my Sienna 2006 key. Before I had him cut it, I was wondering if anyone knows if a special key cutting machine is needed vs a generic key cutting machine.

Thanks!

I have a 2007 LE AWD. My key has a dot on it. I got a blank key from eBay. Had my local locksmith cut the key for $3.

43675


Did the open and close door to get the key and fob program. My vehicle only has the automatic power sliding door on the passenger side. After programing, even the power sliding door works on the new fob. Really happy everything work out.

I thought the power sliding door button doesn't work after the programming. I figure I will need to fire up my Techstream to see if I can program it. After second test, everything works.

I bought an oem key blank and oem 6 button transponder (used) on ebay for a total of $28 plus key cut at a local locksmith for $5. Programed both in under 5 minutes in my driveway. Sweet. Dealer wanted over $200 for both and programing.

Re: Programming transponder key on 2004 Sienna

For my 2004 Sienna, the instructions here were off by one thing: The doors needed to start closed. What worked for me was:

1. *Close all doors.
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. *Open and close the drivers side door 6 times (leaving the door closed at the end).
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.
This is the procedure I just used, and it worked perfectly. The other orders/versions earlier in the thread did not, for some reason, but this one was dead on! I'm guessing it was the closed door thing.

I was using a key from "keylessking" on ebay, on a 2008 Limited AWD.

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.
Just bought a 2008 with one key and will confirm, this process works as described; I just programmed two new key/transponders.

Also, the part number for the Toyota OEM Transmitter/Key Master is
89785-08020
It was available at my local Toyota dealer for ~$20, and they cut the key via the VIN specs FOR FREE, which I was happy since my previous key was worn out pretty good.
I think the key here is to ask your dealer if they will cut via VIN if you buy their key. I have a feeling most would say yes - the parts man told me if I had brought my own uncut key that they would have likely charged for that service.

So it's up to you if you want to save some $ and buy a cheaper key online/store and have it cut at a hardware store - however I felt having it cut to the VIN specs was most important for me, and felt the price of $20 key/cut was pretty solid - plus just one trip to have both done.

Great thread and info !

Guys, for those of you who also dabble in DIY stuff and would like an excuse to buy a pretty decent OBD2 scanner, you can program keys for many cars with an Autel AP200 OBD2 scanner. I programmed a 2013 Corolla key with it. You can pick them up for about $70 on Amazon, and it has a nice batch of vehicle-specific modules like brake bleed, TPMS reset, SAS reset, and other functions that normally don't come on a lot of the consumer-grade tools. I've programmed a key for an 08 Sienna the manual method, and it works, but a key tool like this might be simpler. Just FYI.

How did you clear all the fobs in the car computer? Thanks.

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?
Start all over again - one key at a time. It is entering that specific key in the ignition - read by the ignition switch code reader .. into the computer ..
