Wj Shortcut to a new key?

Hello,

I have read a lot on these forums about the key system in the WJ. I have only one key with the chip, and instead of paying a lot of money (I live in Central America, so nothing here is cheap) for a programmed key, I was wondering if this would work:

Suppose I get two "normal" keys cut, then take my good key with the chip and fasten it inside the steering housing, near to the "chip sensor". Wouldn't these normal keys then work?

Yes, I know I would lose some security, but right now I need to have two workable keys.

Anyone tried this?

Thanks!

well you already no the cons.....
so yes this would work, it would basicaly be the same theory as the "ghoast key" for a remote start

QUOTE=billzcat1;wsar10 is right on point on this oil thread - as usual. Anyone reading this would be well-served taking his advice.

It sounds like it should work. The trick would be figuring out where that sensor is and making sure you get as cloas to it as possible.
Keep us posted. I, too, only have one key for my ride and the process of getting other ones made sounds like I might have to have approval from the U.N. or something.

i've seen those uncut keys on eBay for around 20.00 you can buy one of those and take your original key and program it to your jeep and have it cut at home depot or somewhere. I am lucky my Jeep don't have the chip keys.

Don't you have to have 2 working chipped keys to program a new one? I was under the impression you had to. Otherwise, you have to go to the stealership and they do some fancy voodoo.

You are correct. In order to program a blank sentry key, you have to have two existing ones.

See, now I'm conflicted. On one hand, I'm right. On the other, I'm going to have to go through a major PITA to get another key.

Unless the idea proposed by the creator of this thread works...

I hate key based immobilizer systems with a passion... I'm a victim of GM's Passlock II...


Can the stealerships even help if you only have one key?
When I bought my WJ, all I got was a key, the keyless entry key fob, and the title.

The dealer uses the drbiii tool to program the new key's rfid pass code to the skim. They dont need any keys to cut and program a new one.

you can either program a new key by using the two you have or you need the drbii AND the pin for the skim that only the dealer has access to. Anyone that makes a new security key for you other then the dealer is only cloning the signal from the one key you have and can not make a new key if you don't have one.
The receiver for the skim is a ring aground the ignition switch. You need the key within a couple inches of it to work as a ghost key.

You can ask the dealership to print/cut you a key, you just need to give them the vin# and proof the vehicle is yours. They even had the key code on file for my 90 talon tsi.

Wrong. With the right equipment one can create a copy using only one key.

They need the vehicle physically there to program a new key to it.

Fastening your programmed key inside the steering housing will work. There are other options, but this one is the cheapest and easiest.

Call me crazy, but I have a hunch that it's in the general vicinity of the ignition switch. No time right now to get into the details of why I think that...
