How to program a 2nd key?

Can anybody tell me and confirm a method of how to program a 2nd master key?

I found this

"Add Duplicate Key-
Requires one working Toyota/Lexus Master Key.
1. Make sure all doors and windows are closed.
2. Insert Master key into the ignition cylinder.
3. Cycle the ignition cylinder from ON to OFF, five times
4. Open and close the drivers side door six times.
5. Remove the Master key and insert the new duplicate keys.
6. TURN THE IGNITION CYLINDER ON.
7. The new key will be registered after 60 seconds. The theft
light on the dashboard will go out, indicating that program-
ming has been completed."

On an old post, but tried it a few times and so far no luck, is there another way or can somebody confirm this is the proper way to program the KEY not the FOB, I already got that programmed..

 

as far as i know you can't do it... the dealership has to.. and they know that, so they charge $80 to program it...

if i am wrong, which i hope, someone PLEASE correct me...

 

id like to know also. Cant hurt to know

 

bumped

 

The dealership has to do it. Same thing i wanted with my honda accord. if the key is chipped it has to go through a dealer.

 

gotta do what ya gotta do i guess...

 

It only takes them a couple of minutes. Test it before you leave.

 

When I got my wife an '02 Rav4, we had to take to the dealer to get a replacement key, and they quoted us $30 for the key and $50 for the programming...bought the key, took it out to the tech, and he programmed it, then said 'never mind the fee, no problem', so he did not mark it down on the sheet.

Sometimes you just get a good guy working on your vehicle...

 

yeah, my service guy at the dealership today said it would cost $100 bucks, but he could do it for me for $50.. I have already programmed the FOB and got the key cut, whats the big deal? it takes like less then 2 min to program.. why not free WTF?!

 

i found this

I If you are programming a black key from a black key, do this:
1. Insert old black key into ignition. LEAVE THE IGNITION OFF THE ENTIRE TIME.
2. Pump the gas five times
3. Pump brake six times.
4. Remove old black key from ignition.
5. Put new black key in ignition.
6. Pump gas one time.
7. Let the truck sit like that until the security light quits blinking
If it is a grey key, do exactly the same, but pump gas 4 times and brake 5 times.

 

hmm, any toyota techs in here that could offer any input??

or anyone that has tried this?

 

or where to get original bin files to program the ecu with or software to program it

 

if u get a new ecu exact same model, do u have to program your keys that u already have to it or do they work on a seperate computer?

How to get a key blank

I bought the key blank from a seller on Amazon and there was no small dot on the key blade at all but it works.Those found on ebay might also work.
So just buy the cheapest one which says "for 03-09 4runner"
Should be less than 20 bucks shipped.

How to cut

I at first went to walmart but they refused to cut it because I didn't buy the key blank from them. Home depot and lowe's did the same thing.
So I asked a local locksmith and he did it for just 5 bucks. (just FYI those keys are made of brass, not steel, so most locksmiths would be able to cut them.)

How to program

Actually it's a super easy if you still have one master key that can start your 4runner. There was a pdf somewhere about how to do it on a Prado but
its not very clear(it would ask you to remove the key from ignition 3 times without mentioning putting it back in at all) so I'll try to provide a clearer one here:

1. Take the new key and one master key that can start your 4runner(old key) into the 4runner with you and close the driver's door.(immobilizer light should be blinking)

2. Insert old key, remove old key, Insert old key, remove old key,
Insert old key, remove old key, Insert old key, remove old key,
Insert old key (immobilizer light should be off from the first insertion)

3. open and close driver's door six times (immobilizer light should be off)
Step 2 and 3 need to be done in less than 35 seconds(pdf says 35 seconds)

4.remove the old key. (immobilizer light should come on(steady on, not blinking))

5. insert the new key(immobilizer light should be blinking)

Then just sit there and wait, after about one minute the blinking immobilizer light should go off and you're done.

Whole process need to be repeated for any additional keys, the just programmed key could be used as the "old key" for the additional keys.

If there are 5 master keys registered with the immobilizer, it won't accept any more(and I don't know how would it tell you this, so just do a erase if you can't get it to work after trying for a few times). You have to erase them using a similar method(bring in just an old key, insert+remove one more time and open+close one more time, after the 7th close of the driver's door the immobilizer light will stay lighted for one second, remove the old key quickly after that and all but that one you just removed are erased.)

If you don't have any working master key(meaning you only have valet keys). Then I've no idea what could you do other than ask for help from a dealership.

Total cost is less than $25 if you still have at least 1 working master key. Less than 1/5 of what my local dealership wants.

Hope this would be useful for those in need, please post your results if you decided to give this a try.

 

how about programming a valet key?

The transponder in the key has to be programmed into the ecu.
While many fobs can be self inserted, most keys can not.
Off the top of my head, only some newer GM keys can be done by yourself. Only the ones with a cross and circle "circle plus" and only if you already have two that work. I have tricked a few to accept a second one by pretending the first key is the first and second.
Toyota does not have a reliable way to insert new keys without either the toyota tool, or a locksmith with a tcode or some other system that is not cloning transponder keys.

Ive worked in a few shops, and have charged anywhere from 45-80 for the use of my machine to program a key you bought.
Be careful, some sites sell fake keys that have either no transponder or the incorrect one.

I would call some local auto locksmiths, get some quotes from them.
should be about 60, depending on where you are.
