One of the more frustrating things for me is when someone, or some company, attempts to control me. Typically having the desire for less responsibility, I have no desire to control individuals in this way. Recently, I started looking into what moving my alarm system to a new monitoring service would entail. The primary goal included eliminating the dependence on a landline and getting the flexibility to do reconfigurations myself. I own the alarm system and I felt like I should be able to make those changes.
Upon investigation, I found that my alarm system was a bit challenging to reset the installer code. Searching the Internet yielded several options to try–1234, 9876, 4112 and 6112. Unfortunately, none of those worked for my system and a call to my current alarm service company was met with, “We don’t provide those, we want to protect you from
making accidental changes.” They eventually agreed to try to change the code to another value and called me back a few times. Eventually, their remote effort fizzled out, but I’m
sure they would’ve changed them with an on-site visit and a $75 service fee.
A few searches on the internet suggested copying EEPROMs or analyzing them. I fo
und that my unit used a MIC24LC64 chip and started researching ways to read it.
Disclaimer: Use this process at your own list. It worked for me, but I practiced the process on a separate alarm panel that had no value. Removal of and reading of the EEPROM may result in a damaged chip or loss of configuration if it is not done properly.
EEPROM Reader and Software
For me, the biggest challenge was getting an EEPROM reader working with my computer. The EEPROM reader that I purchased is a “SMAKN® USB Port 24CXX EEPROM Programmer Reader Writer to 24C1024 for XP VISTA WIN7” that I picked up from Amazon for roughly $10. It is cheap and also lacking documentation and software. Getting the software working and reading an EEPROM was a bit of a challenge. My first recommendation is watching this video from YouTube.
