Do individual garage door openers have same codes?

Question

so my garage door opener got stolen out of my car. It's a sears craftsman 1/2 hp about 8yrs old, i went and got a new opener from sears, but my question is about my wifes opener. does it have the same code as the one that got stolen ?or are there diferent codes for each individual opener? I already reprogamed the new one and the key pad and all that Im just wondering if the one that got stolen can still work because it has the same code as my wifes. if someone knows about this stuff , thanks in advance.

Answer 1

Being that old, it probably has a specific code. There should be a spot on the motor housing with a wire coming out (the antenna) that is connected to a cicuit boad that has either a 9 or 12 step switchboard.  That's your code.  The switches can be moved to change it (if your worried about security).  Buy a replacement remote.  It'll have the same 9 or 12 step switchboard inside it.  If not, it's the standard type of remote theses days that use a rolling code that may or may not be changeable

Answer 2

Why would someone "steal" an (I'm assuming " remote" since it would be pointless to keep the "opener" in your car.?), unless they wanted to get into the place it opened? Otherwise, wouldn't they "steal" the whole car?

Answer 3

Separate door openers on the same garage usually have different codes to open an individual door.  If your stolen garage door remote opener was keyed to open BOTH of your garage doors, but you bought a new remote and keyed it differently for just YOUR door, the stolen could still open your WIFE'S garage door, providing the thief drove by your house some night.

Answer 4

All Sears/Craftsman overhead openers manufactured after 1993 store the codes from the handheld/visor clip-on remote controls in the memory of the overhead motor unit.  In order to prevent a lost or stolen remote control from being able to open your garage door, you must clear the memory in the overhead unit.  

The same red, orange, or green colored "smart/learn" button you used to program the replacement remote control will be used to clear the memory.  Press and hold the smart/learn button until the small LED light above the button turns off (approximately 6 seconds).  Once the LED turns off, release the button.  Test by pressing a button on an existing remote control.  The opener will not run.  Reprogram your remote controls and keypad, and you can be sure that your garage is secure.  

If you would like, you may test the theory by clearing the memory, reprogramming only one of the two remote controls you have so that it is working.  Press a button on the other (not yet reprogrammed) remote control, and again, nothing will happen.

After clearing the memory, the opener will only respond to remote control signals that have been reprogrammed.  Because all Sears/Craftsman remote controls manufactured after 1993 transmit a code that is specifically unique to each individual transmitter, the stolen remote control will not open your door.
