So, I'm not paying $100 to get a new key made by FORD(TM) dealership.

I only got one key when I bought my car.

How exactly does this chip crap work?
Can I just glue my old key (it's bent and needs replacing anyways) near to my steering column and then get this,

Is there just some sensor in the lock cylinder looking for a signal from a chip inside the plastic thing?

I'd rather pay $3.44 for a blank vs. $50-100 for a new key and programming from FORD or a locksmith.

edit: 2001 Focus SE if you require that info.

Or just drop my chip in here,

You need to 2 keys to program a new key yourself. And you have to be able to insert both keys into the cylinder and turn. Most larger locksmiths that specialize in car lockouts will have the computer equipment needed to code new keys for PATS2 and will charge less than Ford.

Yes, ok. I know.

But the transponder is inside the little plastic thing no?

How is the signal received?

Yes, the chip is inside the plastic part of the key.
You could have a key cut and just keep the key with the operating chip on the same key chain.
It should be close enough, and if not then off to Ford!

Cool, or just tape the operating chip onto the column I guess?

Yes, that'll work, but it's less safe
