We have a Alarm Lock DL2700 series lock. I need to change the Master Code but it does not work by the process given in the Programming sheet.It does not accept the new code.

I will give you the link to the page with all the info that you need for installing or reprogramming your lock:

This is the website for Alarm Lock, the manufacturer's, tech literature page:

http://www.alarmlock.com/tech_library_instruction_manuals.asp

Notice that links on that page are of the .pdf filetype. That means that you need to have Adobe Reader or similar installed on your computer to view them. So if you are unable to view a file, download (for free) and install Adobe Reader first. You can get it here:

http://get.adobe.com/reader/

Also, find out if you are dealing with a D2700 or the newer enhanced version. Press any 2 buttons and *,if you get a green LED and 6 beeps it is the new version.

If you are unsuccessful in programming new codes from the info provided above, I suggest contacting Alarm Lock for technical assistance by phone: 1 800 ALA-LOCK.

Good luck--and please provide feedback if this helps!

I urge you to read through and follow all steps of the installation and programming instructions found at this link:

It is a PDF file, requiring Adobe Reader be installed on your computer to open it. If you don't already have that, : http://get.adobe.com/reader/

I noticed that bad things happen if you push any buttons with the battery removed from the lock; that may have been your problem here.

In the event that you go through the whole programming process and continue to have no success, there are links on this page: http://www.alarmlock.com/tech_library_instruction_manuals.asp
to "tech support" and "contact us" for more information from Alarm Lock.

I hope this helps. Good luck!

The lock is probably in passage mode, enter master code then press A5A this should bring the lock back to normal operating mode.

I have had this happen on a 3500 and I had to replace the keypad assy. But, you may want to try to restore factory settings just to see if it resets. Disconnect the battery pack and hold down any number key for 10 seconds (this bleeds off any charge that may be in the capacitors). Reconnect the battery and within 3 seconds, press and hold the "A" key. After hearing 6 beeps, release the "A" key and wait for 5 seconds for the lock to re-lock (listen for 1 beep and red LED).
If successful, this will reset factory settings, which means the master code is now 1 2 3 4 5. If you need a programming manual, go to www.alarmlock.com At the top of the home page click on "support". Scroll to the bottom of the support page and click on Technical Library. Scroll down that page and find "trilogy DL programming manuals" and under that click on "download DL2700 enhanced instructions". I hope this is some help!

First you need to know if you have a standard 2700 or the new enhanced version, it makes a big difference. Press any 2 buttons then star, if you get no response it is a standard version, if it beeps several times it is the new version. If it is the standard version, disconnect the battery and press any button. Now you are at factory default. Reprogram the master code, remember the master code and the operating code must b e the same length. 12345 A 1 A new master code A new master code. The master code is the only code that needs to be entered twice during it's programming. To set a manager code press; master code A2A new manager code, to set a new user code; enter master code or manager code A11A new user code. The programming must be done during the lock's unlock window so write down the procedure you intend to use to make things go quicker, if you need more time you can change the unlock window, it is probably set at the factoy 5 seconds. Press master code A45A4, this will give you a 20 second window to program the lock, when you are finished change the lock back to 5 seconds, press; master code A45A1, keep the open window short to conserve batteries.
