I have a craftsman garage door opener, of which I tried to program a new remote. but it did not program. in the event I accidently errased my keypad password. How can I reprogram the keypad, i cannot...


Hello there,
It actually depends on what you are trying to program. And these instructions apply only to openers that do not have dip switches on them.
Remotes: push don't hold the colored learn code button all models have different colors. After pushing the button hold the remote behind your back and push it three times. On the third time the door should run.
Keyless Entry: Program the code you want into the keyless. Push the colored learn code button and then enter the code and push enter three times slowly. on the third time the door should run.
Home-Link. Hold the two outer buttons until the blinking pattern changes. Then hold the button you wish to program and point and click your remote at it. Push the colored learn code button and push the homelink button three times.
There are two models of the Wireless Keyless Entry System, the 740CB and the 940CB. The 940CB is for use only with Security+® garage door openers having an orange/red smart/learn button. The 740CB will work with all openers manufactured since 1990 that have a yellow, white, gray, or green smart/learn button. It will not work with Security+® openers.
To program the keyless entry, first locate the smart/learn button. On our chain drive models, this button is on the end farthest from the door. On our belt and screw drive models, it is on the right side as you face the door from the opener. You simply press and release the smart/learn button. You now have 30 seconds to enter your four digit PIN number into the keypad and hold the enter button for five seconds. Wait one minute and test the keyless entry by entering your four-digit PIN number and pressing enter.
With some Security+® models, you can also program your Model 940CB Wireless Keyless Entry without climbing a ladder, right from your Multi-Function Control Panel. Simply enter your pre-selected code and press and hold the enter button on your Keyless Entry. Then press and hold the light button and the pushbutton on your Multi-Function Control Panel. The garage door opener lights will flash to confirm that the Keyless Entry has been successfully programmed.
Hope this helped you solve the problem. All the best my dear friend. Elect_Comp

I dont know where to find the unlock code for the keyless entry on my 1993 mercury villager?


The only thing you can do is see if the dealer can get the code using the vin, otherwise you will need to replace the module for the keyless entry, i'm not sure if this year can be reprogramed.

I need to reset keyless entry lost the orignal keyless. I know to turn ing. on and off 8 times. Then what do I do?


You can not reset the the keyless entry as far as i know. You can program in a new code but you must have the old code to do that. If you lost your code card go under the drivers side up inside under the radio. in the center above the hump. You may need to pull the carpet back or even some insulation. There you will find the module with a white tag on it that gives you the 5 digit code to your keyless pad. otherwise you will need to take it to the dealer for reprogramming.

We have a Chamberlain Whisper Drive Plus. The keyless entry stopped working, suddenly. I have changed the battery, not the problem. I cannot get it to work, and cannot get it to reprogram. The keypad lights up when buttons are pressed, but when I press "Enter" the whole keypad flashes for about 30 seconds and then just goes dark.

I can't find the keyless entry code for my 2004 ford freestar


The code is on the fuse box under the dash near the hood release. On my van there are two bar codes on a sticker attached to the fuse box. Under the first bar code, on the right side is the 5 digit code (bring your glasses the numbers are really small). After you get this code, just search the internet and there are plenty of forums on programing the keyless remote and also adding your own unique number to the key pad entry.

Good Luck

Reprogram a keyless entry remote control for a liftmaster


MOST OF THE WIRELESS KEYPADS YOU DON'T NEED THE OLD CODE TO PROGRAM A NEW ONE.
JUST PRESS THE LEARN/PROGRAM BUTTON AND RELEASE YOU NOW HAVE 20 SECONDS FOR HER TO PUNCH IN THE CODE SHE WANTS AND PRESS AND HOLD ENTER. THE NEXT TIME SHE PRESSES THE BUTTON THE DOOR SHOULD WORK.

NOTE IT WILL WORK FOR ABOUT 20 SECONDS AFTER ENTER IS PRESSED THE FIRST TIME. AFTER THAT YOU NEED TO RE-ENTER THE CODE AND PRESS ENTER.
PROBLEM SOLVED HAPPY NEIGHBOR!!
