Concord Express Hard EPROM Clear - Does it reset Dealer code?

[dpvwia@xxxxxxxxx]

One of the quickest, least expensive fixes for this is to buy a new Express=
 board only on eBay for $45 or so.  First download the installation program=
ming manual (not just the user programming manual), and write down all the =
existing system settings - mostly the sensor settings.  Then walk yourself =
through the installation manual as a dry-run to make sure you have all the =
info you need.  Then take a bunch of photos of your current board so that y=
ou know how all the wires are connected (maybe make some tape labels for ea=
ch before disconnecting).  Then you disconnect the system power and back-up=
 battery, the all the other connections.  Remove the old board, put in the =
new one and follow the installation manual, using all the info and photos y=
ou recorded earlier.  Takes a couple hours and maybe a couple visits t this=
 forum, but pretty straight forward.  All the codes are the defaults indica=
ted in the manual (1245, 4321, 12345, etc.) so then you can change them to =
whatever you want - and you're in control again!
