nah man, trust me we both heard it, simultaneously when i hit the button we heard both cars unlock. As far as it being a joke, maybe, but its not like i held my key out and pointed it at my car to make it obviousto what i was abt to do. I usually just hit the button while my keys are in my pocket, or hanging from my belt.

I know when i unlock my car door on my stang with the remote the head and tail lights go on. Did it do that for both of your cars?

When i unlock my car the lights dont do anything, only when i lock my car do they blink.

+1, mine dont blink upon unlocking, just locking.
And the horn does not honk unless you hit the
remote lock twice for conformation. Changed
the option via the directions in my owners manual.
Just dont like horn honking allthe time in the
neighborhood. I think its stupid. Like hey, look
at me and my new car. Honk. Honk.[:@]

Thats nothing....10 years ago maybe, my friend had her grandmothers new yorker which she drives often and I had my parents dynasty, both chyrsler products and basically the same car. My key not only opened her doors but it also started her car! Hers didnt work on mine though for some reason...

Diabolical!

A friend of mine used to have an old corolla. His door key would open about 1 in 5 other corolla's doors.

Well maybe Ford thought it would be great to intergrate some older/classic cars problems into a car thats shooting for classic/retro feel. [:-]Maybe...

OK, maybe this will help, but it's been a long time since I researched how this works, so bear with me.

Key fobs work on pseudo random generation. For all intents and purposes, it's random as in there is no discernable pattern to the casual observer, but the "pseudo" part will come into play later. Now the car and key fob first start out by receiving the same pseudo random code generator and are synched to the same code. So, when the key fob sends out code "101" (for simplicity’s sake) the car goes, "ah, yes, 101 - unlock". Then, since they both have the same pseudo random algorithm installed, they run that algorithm and both come up with the same "next code" (202, for instance). This is why it's not truly random, but pseudo random - because an algorithm gives them the next code.

Now, what happens, if you're miles away from your car and accidentally hit your key fob? It sends code 202, and goes to the next code (879) but the car isn't in range to receive it, so as far as the car is concerned, the code is still 202. Well, because the code is pseudo random, and not truly random, the car not only knows the current code, but can predict the next one, and the next one, and the next one - in most cases it will calculate the next 256 possibilities and be prepared to receive them from the key fob. Once the code 879 is sent when you're back in range, the car goes, "OK, I know where we are at now" and resynchronizes itself to the new code. (Yes, if you hit your key fob 257 times while away from your car, it won't work the next time and you need to take it to the dealer to be reset).

So, bottom line, because the car knows the next 256 possibilities, it is theoretically possible for you and your friend's car to be accepting of the same code, but there are 1 TRILLION code combinations...so the odds are still against it.

I hope that was more interesting than boring, and I apologize if this isn't 100% correct - like I said, it's been a long time since I researched this and I'm doing it all from memory.

Cheers!
