You can't program any chips, they will only emit a certain frequency and it cannot be changed.I was under the impression that IMMO3 chips could only be programmed once.
I am reading a lot of people reprogramming old chips over again.
Is this possible?
Immobilizer don't work on frequencies , it works on data what is being read from chip.When programming a key, you are actually programming the car to allow certain "chip" frequencies to allow it to run. So if you have three keys each key will have a slightly different frequency, but your car will allow any one of those frequencies to start it and allow it to run,
It can be reprogrammed more then one time but in same cluster( immobilizer)I was under the impression that IMMO3 chips could only be programmed once.

He was the locksmith at the San Pablo GTG on March 13 in the West Coast forums (there's a GIANT thread).Do you got the name of this person? Do you know if he can cut if given a VIN? The only place here in town who will do it for me besides the dealer wants almost $100.
Wow, this all completely incorrect, fur future reference anyone reading this thread ignore all of it.You can't program any chips, they will only emit a certain frequency and it cannot be changed.

Take your key and put it into someone else's car, (provided the blade is cut to the new car) you can turn the car on, but not start it cause the cluster does not have that specific frequency stored as a "safe" key so it shuts it off within a few seconds
So to answer your question No you cannot reprogram a "chip", but you CAN program your car to learn and store an endless amount of frequencies, but I think it is 5 at any one time, meaning you can only have 5 working keys for your car (i might be wrong with that number), if you loose all 5 of them you can erase them all from the cluster (so if someone find your keys months later they will be no good anymore) and reprogram 5 new ones???
Another way to look at it is, I could take my keyfob, remove the blade, put your blade in my fob, so the new fob would have your blade but the immo would be programmed for my car,
I can then put the key into your ignition(cause the blade would match your ignition) turn it on and program the car to accept my immo and it would allow it to run.........and it would take my less than 10 minutes to do it!!!
Hope that helps

His username here on the forum is NFSTDI and he's a really nice guy. He's based out of Berkeley down here but if he can help you out I'd bet he'd be willing to mail you a key. You should drop him a private message to ask.He was the locksmith at the San Pablo GTG on March 13 in the West Coast forums (there's a GIANT thread).
So your saying I can't take my passat key and program it to run my jetta because it has already been programmed once??I am certain you are wrong on this one!!!Wow, this all completely incorrect, fur future reference anyone reading this thread ignore all of it.
How does it read the data on the chip then???Immobilizer don't work on frequencies , it works on data what is being read from chip.
Remote for locking doors works on frequencies.
Please don't give wrong info to people .
No you CAN NOT on Immo3,immo4 and 5 generation unless you take all data from one cluster to other.Other wise USED KEY on immo3 CAN NOT be reprogram to other car.So your saying I can't take my passat key and program it to run my jetta because it has already been programmed once??I am certain you are wrong on this one!!!

Thanks Skully. Sending him a message now.His username here on the forum is NFSTDI and he's a really nice guy. He's based out of Berkeley down here but if he can help you out I'd bet he'd be willing to mail you a key. You should drop him a private message to ask.
Because key chip takes data( VIN, Immo id) form immobilizer and store it in chip.If nothing has changed with the key, why can the key not be recycled and used with a different vehicle?
Any additional insight?
I followed JetBlue's instructions to the letter (???)I used the Vag Tacho 2.5 program to program a new key for my 2002 Jetta. I am writing this in hopes that it will help others to get keys programmed without going to the stealership.
I am going to go over what I did to program my new key, If you follow these instructions, it is at your own discretion and I am in no way responsible for any negative consequences.
1. I ordered a spare key blank some time ago and it had been sitting in a drawer for a while. This is a key with an immobilizer chip, but no FOB.
2. I also bought a vag-tacho cable that came with the vagtacho program, it also had been sitting for several months.
3. I first needed to get the key cut. I tried 3 different VW dealers and ones key-cutter had been broke a while and the other 2 did not have a key cutter. They only ordered keys using the VIN that came precut. Inquiring I got info that a Valet key would be around $65 and a flip-key with new FOB would be around $165 plus programming ($ didn't ask).
To get the key cut I had to go to the AUDI dealership where I was there for a total of 15 minutes. The trace cut the blank from my only key for a total w/tax of $8.74.
4. After installing the program on my laptop, I plugged it the tacho cable and went to the car, Plug in the OBD-II plus into the connector, the green light on the cable will be lit. Start the Vag-Tacho program, after it is up an running, using your old key turn the ignition to on, but do not start the car.
5. On the program go to top, click on select ECU and put the check mark next to 'VDO New'
Now select the button labelled 'Connect Selected ECU'. I first got a message telling me 'Selected ECU Not Found! Try again or Select other ECU!' Going with the first option I tried again by clicking on 'Connect Selected ECU'. I had to do this 3 times before it finally connected and gave me an OK message.
6. After Connecting 'OK', There are more options that become available on the bottom buttons. I first selected 'Read PIN'. replied okay reading, my four digit PIN was revealed and I commited it to memory.
7. I then was ready to proceed with the programming of the NEW Freshly cut key. To begin make sure that the ignition is on with the OLD ALREADY WORKING KEY. Click on 'Program New Key'. A box will pop up with '0000' displayed where your four digit PIN gotten from step 6. I entered the PIN and did not change any other options. Erase all keys WAS NOT selected. The Channel defaulted to 21 so I did not change it.
8. Click on program new key, the program does its magic, my immobilizer idiot light was now flashing. The program then tells you to turn off the ignition, insert the NEW TO BE PROGRAMMED KEY, turn the key back to on, but do not attempt to start the car, Wait 5 Seconds. After 5 Seconds, my immobilizer light was off and I now have 2 keys that will start my car.
*****I originally started with the NEW KEY in the Ignition, I turned the key off and back on to program it. This ends up disabling the original key. I now had to used the NEW KEY and follow the correct directions to reprogram my old key, It worked flawlessly, without a hitch first time. **************
Hopefully this will help someone who like me was searching for this info and you will not have to do as I did and put pieces and parts from different locations.
Good Luck!!
