You can't get it open without either knowing the code, or destroying it (as in cutting the shackle, or some such destruction). There are truly 10,000 codes (combinations) available. If you have the time, you can systematically run through them until you hit on the one that works.

Help truck was stolen, I used remote control to "teach" truck how to open door... I reset door opener and relearned the remote..my question is do the remote have a new entry code when I learn, or remote is...


Ounce you reset ALL code of the garage door opener (engine hook up to the ceiling of the garage that open up the door), ounce you press the reset button on the unit, it disable all transmitter (portable or the one install in your vehicle). Your garage door opener has a receiver in it and your all units that you press on to open the door are the transmitter, so by pressing the reset button on the door opener, you erase all codes of all the transmitter that where programmed to open-up that door.

So if you teach your vehicle using a portable unit and you now reprogram your new vehicle with the SAME portable transmitter, then yes who ever has your stolen vehicle can come back with your stolen vehicle to your house and open up your garage door since you re-programmed the door opener using the SAME transmitter same code sent to the unite to active it).

Buy a new transmitter to re-programmed your new vehicle

I bought a new Chamberlain garage door remote control (Model 953EV/EVC) but my garage door opener is date 1991. Can I get this remote to sync with it? I have one remote dated 1993 that came with the...


The 953EV/EVC remote is designed to work with garage door openers at 315MHz (more or less). Your older unit doesn't work at that frequency. I'm not positive but it could be 300MHz.

You need a retrofit unit to use the new remote. See https://aclickawayremotes.com/Liftmaster/355LM-2-315-Mhz-Garage-Door-Opener-Conversion-Kit/index.html for one that works with Chamberlain units.

I hope this helps.

I need to reset my keypad, bought a new house...do not know the old 4 digit code, need to reset and set my own??


Locate the smart/learn button on the rear of the motor unit near where all those white wires go. Press and immediately release this and then walk over to your keypad and key in any 4 digit code you like and press enter.

Have a Craftsman 1/2 HP auto gargae doors. Lost power during a snow storm. Once power was reconnected only thing that did not work was garage doors. Is there a reset button somwhere....can't see one.


There isn't a reset button. Check the house circuit breaker. You may have had a power surge and that can damage the logic board printed circuit. Check the logic board for missing or burnt traces especially around the small transformer.

Bought a house and it has a craftsman keyless entry pad but I dont have the password to reset it...Is there a way to reset it and enter in a new passcode???


On the back of the motor unit you will find the smart/learn button near where all those white wires go. Press and immediately release it and then walk over to your keypad and key in any 4 digit number you like and press enter. Easy as pie.

Universal garage door remote


I have a feeling your neighbor operated their door opener when you were programming your new clicker. Try erasing the memory of your opener and then program the clicker again making sure your neighbors do not operate theirs at the same time. To erase the memory hold the smart/learn button in for 10 seconds.

Craftmans remote garage door opener does not work


Hello,

Most likely the battery is dying and needs to be replaced.
You can open the rear cover and replace it, they should have the battery you need at wall greens!

Once the cover is off make sure the switchs matches those of the Garage door sensor itself other wise it will not open.
It should tell you how to do this in the manuel that came with the unit.

If this does not work call tech support at the 800 number provided to you in the manuel and they will walk you through it. Most likely you bought this from Sears, craftsman is a Sears product.
