Its common an alarm system owner does not know the Installer Code which allows them into Program Mode of their control panel. The installing alarm company knows this special installation code required to make system changes but may not have shared it despite their customer owning the system.  Dealers do this frankly to make it as difficult as possible for customers to change to a lower priced monitoring company.  SafeHomeCentral however provides all documentation and system codes to our customers so they can easily add devices themselves (DIY) or change alarm monitoring providers with minimal hassle.  Companies such as ADT, Brinks, ProtectionOne many times use the same Installer Code on all installations making it easier for their service technicians but unfortunately will charge a fee to reset the Installer Code back to the manufacturer default.  This fee could be $100 even if they can reset the code remotely.

For those just moving into a home with an existing alarm system It’s very possible the previous owner did not leave the Master Code which allows you to change user passcodes.  This happens frequently because they assume their former alarm company will set the new owners up with alarm monitoring and change all of the existing security system passcodes.

The good news with Honeywell alarm systems is there is a “back door” into Program Mode to reset the Installer Code and Master Code.  If your keypad says Ademco its now Honeywell (acquired in 2000).  ADT for years has used Honeywell/Ademco systems so don’t be fooled by the ADT label on the keypad.  Its probably a Honeywell product. 

The default Installer Code for all Honeywell/Ademco alarm panels (hardwired and wireless) is 4112.  You can always try the default Installer Code first but it would be unusual for a security dealer to not change the code as part of their installation procedure. 

If you have an ADT SafeWatch Pro which is a rebranded Honeywell Vista control the default Installer Code is 6321.

If you own a Honeywell Lyric Controller there is no way to reset the Installer Code without already knowing the current Installer Code.  If you don’t know the current Installer Code your only option is to get the code from the last dealer.  Unfortunately if they won’t release this code to you the panel can NOT be monitored by any other dealer.

Vista Keypad (6160)

Vista Control Panel

Vista Transformer

The process for resetting the Installer Code for Honeywell Vista panels is fairly easy when there is a standard 6150 or 6160 style keypad in place which is typical.  If you have a touchscreen style keypad such as the 6280 or Tuxedo this backdoor method will unfortunately not work. 

For hardwired security systems there will be a metal enclosure located somewhere out of sight such as in the basement, closet, garage, but always in a protected space.  Alarm panels are low-voltage devices and use plug-in transformers rather than direct 120VAC wiring.  The transformer will be close to this panel enclosure and usually screwed to the outlet cover plate so no one unplugs the transformer accidentally disabling the alarm.  The system’s backup battery is inside this enclosure and can easily be disconnected which will be needed to reset the Installer Code.  All configuration/programming is stored on nonvolatile memory so there is no danger of losing anything when power is lost.  Here are the steps:

• Unplug the 16.5VAC transformer from the 120VAC unswitched wall outlet.  If you can’t seem to locate this transformer you could also carefully remove the wire from Terminal 1 on a Vista panel.  Be careful to not short out the transformer by touching the metal enclosure or any other screw terminal.
• Unplug the backup battery located in the metal enclosure.  Just slide either the Red or Black wire off of the clip on the battery.  There is no need to disconnect both the Black and Red, just one.
• Wait ten seconds then plug the battery back in.  Within 50 seconds press * and # simultaneously until “20” or “Program” displays on the keypad screen.  You are now in Program Mode!  If you wait longer than 50 seconds just unclip the battery and start over.
• Assuming you are in Program Mode hit #20 and the keypad will display and beep the current Installer Code one digit at a time.
• If you want to change the Installer Code hit *20 and enter four new digits.
• Hit *99 to exit Program Mode
• Test that the Installer Code allows you into Program Mode without power cycling the panel.  Enter [Installer Code] 800.  If sucessful “20” or “Program” will display.
• Exit Program Mode.  Enter *99
• Plug the transformer back in or reattached the wire to Terminal 1.

Once you have a valid Installer Code you can reset the Master Code which allows you to add or delete alarm passcodes.  To change the Master Code enter the following:

[Installer Code] + [8] + 02 +[New Master Code] + [New Master Code]

For clarification User Code 01 is the Installer Code, User Code 02 is the Master Code, and regular user codes begin at 03.

Honeywell Lynx Touch L7000 Wireless Alarm System

Follow these steps to reset your Installer Code if using the Honeywell Lynx Touch L7000 wireless security system.  The L7000 is an “all-in-one” wireless alarm system meaning the keypad, control panel, wireless transceiver, siren, backup battery is all contained in one housing.

• Unplug the low voltage transformer from a nearby 120VAC outlet.  If unsure where the transformer is located open the front of the Lynx Touch and disconnect one of the wires connecting the transformer to the L7000 motherboard.  You can unhook the front face of the L7000 by depressing the two clips at the top of the system.
• The L7000 will start beeping when the face plate is unclipped (tamper alarm).  Just hit the green HOME button to silence.
• Wait 60 seconds then disconnect the backup battery battery from inside the L7000 by unhooking the white plug on battery.
• Plug battery back in and reconnect transformer wirer or plug transformer back into wall outlet.
• Close panel and while the panel begins to boot (black screen) HOLD DOWN green Home Button.  Do not release until the Green “Ready To Arm” strip at top displays (not the red “System Standby” banner).  This may take 60 – 90 seconds so just keep holding.  If you let go start again.
• Hit Security Icon
• Hit Arm Stay
• Hit Clear followed by “00”
• Hit Program
• Hit Installer Code.  This will display the current Installer Code.  You can change this code by hitting CLEAR and four new digits to change the Installer Code.
• Hit Back Arrow to exit.  It will ask if you want to allow installer to re-enter programming.  Select YES!  If you select No then the above steps will need to be repeated anytime you want to get into Programming Mode.

To check panel firmware version level:

• Hit Security
• Hit More
• Hit Tools
• Enter Installer Code
• Select Test
• Version number will be displayed (I think it’s at the top of screen)
• Press back button twice to exit

Honeywell Lynx Touch L5210 Wireless Alarm System

Follow these steps to reset your Installer Code if using the Honeywell Lynx Touch L5210 wireless security system.  The L5210 is an “all-in-one” wireless alarm system meaning the keypad, control panel, wireless transceiver, siren, backup battery is all contained in one housing.

• Unplug the low voltage transformer from a nearby 120VAC outlet.  If unsure where the transformer is located open the front of the Lynx Touch and disconnect one of the wires connecting the transformer to the L5210 motherboard.  You can unhook the front face of the L5210 by depressing the two clips at the top of the system.

• Wait 60 seconds then disconnect the backup battery battery from inside the L5210 by unhooking the white plug on battery.
• Plug battery back in and reconnect transformer wirer or plug transformer back into wall outlet.
• Close panel and wait while the panel begins to boot (white screen).  Once you see System Standby (red banner at top) press the HOME button for three seconds until you see the green Ready to Arm banner at the top.
• Hit Security Icon
• Hit Arm Stay
• Hit Clear followed by “00”
• Hit Program
• Hit Installer Code.  This will display the current Installer Code.  You can change this code by hitting CLEAR and four new digits to change the Installer Code.
• Hit Done then the Back Arrow to exit Program Mode.  It will ask if you want to allow installer to re-enter programming.  Select YES!  If you select No then the above steps will need to be repeated anytime you want to get into Programming Mode.

Honeywell Lynx Plus L3000 Wireless Alarm System

Follow these steps to reset your Installer Code if using the Honeywell Lynx Plus L3000 wireless security system.  The L3000 is an early “all-in-one” wireless alarm system meaning the keypad, control panel, wireless transceiver, siren, backup battery is all contained in one housing.

• Unplug the low voltage transformer from a nearby 120VAC outlet.  If unsure where the transformer is located open the front of the Lynx Plus and disconnect one of the wires connecting the transformer to the L3000 motherboard.  You can unhook the front face of the L3000 by depressing the two clips at the top of the system.
• Unplug the backup battery from inside the L3000.
• Wait ten seconds then plug the battery back in.  Within 50 seconds press * and # simultaneously until “20 Installer Code” displays on the keypad screen.  You are now in Program Mode!  If you wait longer than 50 seconds just unclip the battery and start over.
• Assuming you are in Program Mode hit #20 and the keypad will display and beep the current Installer Code one digit at a time.
• If you want to change the Installer Code hit *20 and enter four new digits.
• Hit *99 to exit Program Mode
• Test that the Installer Code allows you into Program Mode without power cycling the panel.  Enter [Installer Code] 800.  If sucessful “20 Installer Code” will display.
• Exit Program Mode.  Enter *99
• Plug the transformer back in to the AC outlet or reconnect wire on motherboard terminal.

Honeywell Lyric Controller Wireless Alarm System

Unfortunately there is no backdoor method for resetting the current Installer Code on a Honeywell Lyric panel.  If you know the current code just go into Programming with this code and change the Installer Code to anything you want as long as it doesn’t conflict with a current user code.

If you don’t know the Installer Code the current AlarmNet dealer can tell you the code or remotely reset the Installer code for you.  If you don’t have service any longer with this with this dealer many times the dealer will refuse to disclose the code or require an onsite call to change the Installer back to default (4112) along with a service call fee such as $100. 

If you don’t know the Installer Code you are forever locked out of Programming which is needed for adding new sensors or setting up alarm monitoring with a new company.  Honeywell tech support can not help since its a panel lockout issue.  There is nothing they can do remotely to help.
