I did search but can't find info...

Does anybody know how to program the chip on the Tc key?

You can try the following I found online, but from my previous experience with factory transponders this almost looks like its meant to program the remote lock/unlock functions only:
Let us know if this works.

1. Start with the following conditions: You are in the drivers seat.
a. Key is out of the ignition
b. Driver door is open (all other doors closed)
c. Driver door is unlocked (other doors don't matter)
2. Insert and remove the key from the ignition twice within 5 seconds.
3. Close and open the drivers door twice within 40 seconds.
4. Insert the key into the ignition and remove it.
5. Close and open the drivers door twice within 40 seconds.
6. Insert the key into the ignition.
7. Close the door
8. Turn the key in the ignition on and then off.
9. Remove the key from the ignition.
10. The power locks should automatically cycle once to indicate that you have successfully entered program mode.
11. Within 40 seconds of the entering program mode.
a. press both transmitter lock and unlock buttons SIMULTANEOUSLY for a duration of from 1 to 1.5 seconds.
b. within 3 seconds, press the transmitter lock button for more than 1 second and release.
c. If the transmitter has been sucessfully programmed, the power locks will automatically cycle once. If they cycle twice, the remote has not been accepted.
d. If multiple remotes are to be programmed, repeat steps A-C.
12. Open the driver's door.

Thought I might as well add that most transponders I've seen program like this:
- insert original key that starts car, turn to ON, leave on for a couple seconds.
- remove key and insert NEW key, turn ON, leave a couple seconds.
- remove new key, reinsert new key and attempt to start.
- if for some reason after this it wont start, reinsert ORIGINAL key and leave in ON position for several minutes, then start. (to insure that you have at least one functional key)

????????? hahahaha

Yeah, it sounds like quite the dance compared to the honda and for transponder systems I've done...

Stealthtc

This is just for the remote program...

Does the above work?

Whocares05050

what, r u kiding me i didnt think u were serious i thought you were just playin arounf, what the hell would you need to program the transponder for?

scionTC05

if what i've seen most transponder keys have to be programed at the dealership. Just from what i've seen thats all

kileil

Works for many vehicles I've dealt with, can't say 100% for the scions though. Some want to see 2 programmed keys before it will program a 3rd, its a bit hit or miss.

kileil

I'm guessing he had a key cut but not programmed to his car... How this would happen is a bit of a chin scratcher isnt it?

Stealthtc

Could you give me a specific make of vehicles that you had dealt with..

Whocares05050

honestly, what the hell r u all talking ABOUT!

Many different vehicles, I do about 50 remote starters a year if I had to guess and have been doing it for about 5 years full time. I have to trick the transponder in the car to "think" that the key is in the ignition when it is remote started. Sometimes I use a duplicate key, other times I use modules that "remember" the key by reading and storing the info sent by the original key to the vehicle's security/ecu/wherever the comparison code is stored.

If I had to say what makes i outright bypass the most, it would be ford, chrysler, and honda in that order. The programming of the keys comes into play because occasionally when youre messing with the factory transponder system you can cause it to forget keys.

btw: I'm not trying to come off as some install god here at all, i'm still learning new stuff everyday.

Here's an analogy for ya:
Know when you get a new remote for your car, how you have to program your car's alarm to recognize it? Same with transponders in the key. When you turn the key to start your car, theres a copper ring in the column of your car that "reads" the info stored in a chip in your key. If the info is wrong, no startie for you.

Man I feel like I'm post whoring... Anyways, this whole discussion got me interested because I'm sure I'll need it some day. So I looked around a bit more and found this one that looks much more like the usual programming procedure:
****************
FOR 2002+
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 5 times.
4.Open and close the driver side door 6 times.
5.Remove the master key and insert the new duplicate key.
6.DO NOT 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 programming has been completed.
"some 2002 will work using the 1998+ programming."
*****************
BUT they say some toyotas need to have their ECU reflashed (pain) if the above procedure isnt successful at programming the new key to work.

TurboTC

None of the procedures posted online work with the 2005 Toyotas. You can program the keyless entry yourself but the key wont start your car.
I gave up and paid my dealer $45 to program my tC to accept the transponder in my new key.

scion_tC

is the engine immobolizer something easy to bypass by a wood be theif...i know the chip in the key disables it...but this also makes it safer right...and also when u insert the key to unlock the doors does the car read the chip to unlock and lock the door, or only to kil the immobolizer

TurboTC

Without it programed the key will unlock the doors. The engine will turnover but will not start.

I saw someone selling tC instructions on ebay for like $5 or something. Since I didn't need it I wasn't going to pay, but it seems that with all the dealers and folks we have around, someone could let us know what the deal is.

monkeyboy

My dad is a locksmith.... this something that a locksmith could knock out in a few minuetes... I don't have the procedure for doing this with out the machine that jacks into the ecu..... I will ask next time I talk to him...

iowagary

I didn't know your average locksmith could do this kind of thing, but any way you can do it, I just want to know how it works.
