Chamberlain Remote Keypad Model 940EV/EVC - Opens WITHOUT Code
on May 19, 2014
I have had the remote keypad over a year and it's been great, working as described for programming and operation. EXCEPT yesterday we found that you can open the garage door by simply pressing the "ENTER" button, with no codes or other buttons. IF you enter the correct code and ENTER, the door works just as you expect. IF you enter the incorrect code and press ENTER, the door does NOT open. But if you WAIT a while after entering an incorrect code, OR just RANDOMLY walk up to the remote and simply PRESS the ENTER button by itself, the garage door WILL OPEN - NO CODE NEEDED and NO HOME SECURITY. I called Technical Support and re-programmed it as they suggested, and it still malfunctions this way. I will probably replace it and hope for the best because I do like it. I have no clue HOW LONG this operating defect has existed, but my house was accessible for a while now unbeknownst to me. WARNING - Please check the proper operation of your keypad by pushing only the ENTER button with no codes and make sure you do NOT have this design or circuit failure flaw.
