How to add or program sub key?

[medtro]

I have read that our car can accept up to 5 master and 3 sub keys. I searched but didn't find any info on how to add sub key. Anyone knows how to program sub key without buying expensive equipment?

There is a thread on programming in the Electrical section of the forum FAQs. I found it easier and faster to just pay the dealer $80 to program all 4 of my keys; 3 masters and 1 sub.

I have read through that thread, didn't see any info on how to program sub key. I found a lot of incorrect information in that thread though.

I don't know what the advantage of programming a sub key is with these trucks, all it does is not allow the key to enter the programming sequence to program more keys.

Updated the FAQ thread with a new, simpler thread.

Exactly what I want - not able to enter programming mode with the key.

Did you read Post #4 of this thread?

How many people is your truck at risk from getting in it with a cut key that's not programmed that know the steps to program it and need to and have a master key?

Did you read Post #4 of this thread? He started that thread because of my thread.

If you must know, I actually have read the following articles from Locksmith Charley many times and tried them many times before I started this thread:

• http://www.locksmithcharley.com/toyota-obp-e-instructions.pdf
• http://www.locksmithcharley.com/toyota-obp-i-instructions.pdf

I was not able to find the correct instructions to work on my 2004 LX470, which is why I started this thread hoping that someone might be able to help.

I am sorry if you misunderstood my thread as I am seeking your approval to program a sub key. It is not wrong if I don't do thing the way you think it should be done. You just have to get use to it.

Well now that we have the full picture and your MY, if you'll read it again, 03/04 you're likely headed to the dealership. And approval has nothing to do with my post, I'm just pointing out that a valet key has very little practical use. But you go girl.

Your answer is confusing, in post #4 you link a source but now you say the dealer. What is the truth to getting the key programmed?

 

[Trunk Monkey]

Didn't know the MY of truck, but now that we do, 03/04 uses a different transponder that requires dealer programming.

I didn't specify the MY on purpose because I am willing to try any instructions for any model years. Yes, I read what you stated about 03/04, it is simply 100% not true. You were questioning me after I told you what I wanted - not able to enter programming mode. I failed to see what you pointed out there.

Dealer programming not required for 2004 LX470.

Nice. No ability to program a valet?

 

[medtro]

Can't say no on that. However, I will tell you that I don't know how to program valet key.

Curious where you found these instructions? Everywhere I've seen online (and here) says either you're taking a trip to the dealer or it's insert key 5 times, door 6 times. The 7 and 4 are new.

I wrote those instructions. I got the add key instructions from the following video. I posted the same video in the programming thread that was in the FAQ before. I came up with the delete key instructions after reading the 2 PDFs from Locksmith Charley that I posted in this thread.

If it works, it works. Added to the FAQ.
