Program Key for Toyota Sienna





Introduction: Program Key for Toyota Sienna

I did not come up with these instructions on my own. I had programmed keys for other cars pretty easily, and was frustrated the minivan was so difficult to program. I had a locksmith scheduled to come out today, but after he called to reschedule, I found these instructions online. Happy to say it worked.

If you're looking for instructions on how to program a key fob, look here:

Step 1: Buy a Transponder Key From the Internet

The Toyota Sienna uses a 4D-67 key. I bought two for $15 on ebay. These are pretty widely sold. Check the seller's reputation, but they are cheap enough that there isn't much sense for them to be selling fakes.

Step 2: Get You Key Cut by a Locksmith

I took my keys to ACE. They charged me more than most locksmiths, and they did a crappy job. A bunch of the keys I had cut (did more than just for this minivan) didn't work. I'm going to a locksmith next time.

Since they aren't selling the key, they are likely not going to promise the key will work, but locksmiths will typically duplicate keys cheaply.

Step 3: Follow These Steps to Program Your Key

Sit in your van with all doors closed. I opened and closed the door one time to 'clear' the system.

Insert your original master key to key cylinder 5 times and leave it there ('in' and 'out' four times, just 'in' the fifth time).

Open and close driver side door 6 times. Should be closed when you do the next step.

Remove master key from key cylinder, insert your new cut transponder key.

Turn that new key to "ON" position.

Look at that red engine immobilizer light (the red light to the left of the speedometer which is car shaped with a black key in the middle of it). It is blinking.. wait about 1 min and it will turn off by itself.

After engine immobilizer light turns off, remove new key and insert original master key. Start engine.

Now try your DIYed new transponder key to start your Sienna.

    Hi. It worked for my 2004 Toyota Sienna. Smoothly and easy. Thanks. Ah! And I live in Puerto Rico.

    will this work for a 2011 sienna

    Worked great! I did 2 new keys and 2 new fobs using this and another instructable. Total cost, $12 for the keys, $3.50 to cut them, and $35 for the 2 fobs. So $50 total instead of well over $200 for a dealer to do it. Heck yeah!

    Sorry, was a 2005 Sienna LE AWD

    I want to do the same with my mitsubishi, do you know how to get the instrutions for other cars?

    I have a 2006 Sienna xle. If I follow the procedure to program my copy key and it does not work, will it mess up my master key and make me unable to ignite the engine with the master key? Appreciate your feed back. Thx

    I doubt it. I don't think you're actually programming the key. You're programming the van to accept the new key as valid.

    But proceed at your own risk.

    What do you mean by Master Key? I bought the car used and received 2 keys and one was recently lost. I want to replace it. Is the Master Key just the other key I have, or is it a special key?

    Yes, the master key means the one that is cut and already programmed that it sounds like you already have.

    Awesome. Worked great on my 2006 toyota sienna. Thanks for these simple instructions. Saved me $40

    Thanks! Worked Great! I bought the key on Amazon. Home Depot cut for free.
