I grabbed my bag and exited my car. Locked my car, udjusted and started to slowly move away. I hear the mechanism for my car open the lock when she opened her car with her clicker as she went in the back seat for something. is this possible?
Can someone’s car clicked work with yours as well? What are the chances in it happeneing
is this possible?
Well, you did see it happen. It was/is not uncommon for cars with conventional keys to be keyed alike. I once accidentally unlocked and got inside a car that was the same make and year and model (and color) as mine, but my car was actually one row behind this one. I mentioned this to a friend and he said that a buddy of his was a repo man and he had rings of the “standard” keys for any given make/model/year of car. So I wouldn’t be a bit surprised if this same sort of thing happens with keyless entry systems.
I saw 6 cars (all late model GM) hve thier alarm set in the same grocery store parking lot at the same time by someone getting out of thier car. I thought it was one of the funniest things I’ve ever saw, as this was not a large store and about 12 people came out at once to find the lights flashing and horns beeping. Before this I’d assumed that they were all coded differently…but this proved to be false.
Heh, I moved from one apartment complex to another one clear across town.
I went to go unlock my “new” apartment with my key. It wasn’t till after the fact that I had realized I opened it with my old apartment key with no problem what so ever.
Now what are the odds of THAT happening? (I should have bought a lottery ticket that day.)
For manufaturing reasons I wouldn’t guess that the would make more than a hundred or so different key combos. (both remote and actuall key) Cost effectiveness and all.
Do people actually call the alarm keys ‘clickers’? Wasn’t the old TV remote control called a clicker when it first came out?
For isolated incidents, it might be more likely that you thought your door was opened by her ‘clicker’ (key fob), when you accidentally activated yours (although I ain’t arguing. Just offering that up as a possibility).
I, too, have seen this happen with remotes for cars and garage doors. While the iterations of codes available are huge, they are not infinite. With tens of thousands of cars equipped with keyless remotes and millions of daily trials (people locking and unlocking vehicles), it’s not surprising that 2 or more vehicles in close proximity are occasionally expecting the same code.
No, I’m afraid not. You need to see a psychologist. 
You did not say what make and model of cars we are discussing, so it is hard to answer for sure. Also you did not say if the system was factory or aftermarket.
Speaking only for the cars I teach on, the remote has two codes one eight digit and one 16 digits long, both are alpha numeric. These codes are locked into the remote, and the remote has to be programmed into the car using a computer workstation. So on my car, while it might be possible, it isn’t very likely. Other cars makers may not be as concerned with security, and may not have anywhere near this level of anal retentivness. 
The newest ones use rolling codes, 1 in a trillion chance that someone happens to have the same code as you at any given moment, and the next time you have different codes. Can’t capture the code and try to use it.
Apparently my garage door opener is not so modern. About once every 2-3 months my garage door opens when my next-door neighbor opens his door. Not reproducible, but has happened too many times to attribute to coincidence.
An old colleague of mine found that his car was unlocked by someone else with the same make and model (BMW 318). Entertainingly, one was locked, the other unlocked… then the other way round… and back again…
Even more entertaining was later, when the other car had gone away, my colleague using his remote to unlock the car and his alarm going off. He didn’t think he had an alarm. BMW had told him his car didn’t have an alarm. He had to phone the guy with the other car (fortunately they’d swapped phone numbers), and ask him to come back and stop the alarm from going off.
I hear is as keyless entry or simply remote control / car remote. Where did the term key fob come from?
I’ve heard “fob” used ever since I put an stupid alarm in my 1987 Ford Escort to protect it from ne’er-do-wells.
I think owners’ manuals refer to them as keyfobs, no? I know I’ve seen it written in enough places to make it appear in a dictionary somewhere.
It has something to do with the fact that the watch pocket on a vest is called a fob pocket. I am to lazy to google it, however.
Mine calls it a transmitter, and the system calls it remote keyless entry system. Perhaps Keyfob is a brand name?
When I was a young college student, both myself and a friend of mine each had a Ford Festiva. His was an '87, mine was an '88. (I miss that car, but that’s another thread).
His key opened my door, but mine did not open his.
Certainly possible, though relatively low odds. Similar to the lottery I’d guess. I know people who have won some relatively large payouts ($100k), but I’ve never won more than a free ticket.
Hit the button too soon… 
The wife and I call it a “chuckka chuckka”, imagine the sound that some of them make. Calling it a clicker wouldn’t be too far off, and would likely also be a derivative of the TV clicker. We still call that a clicker too, but I’d be upset if it actually started clicking.
