We recently received an inquiry from a customer asking about a replacement for his Magnadyne remote that has FCC ID ELV777K on the back. ELV777K is one of those FCC IDs that appeared on several aftermarket alarm remote transmitters that had different circuit boards inside them and transmitted different electronic signals. Most of the original parts were branded “Carbine”, “Magnadyne” or had no brand logo on the case. Because of the different internal circuit boards, we needed more information about the customer’s original remote.
All of the 1-button versions carrying FCC ID ELV777K used the same internal technology. That part has been discontinued but there is a 2-button replacement remote available that will work in its place.
There are three different technologies used in ELV777K remotes that originally had 2 buttons. In order to determine which replacement remote is correct for these original keyfobs, RUI needs to know the circuit board number of the original remote. Then we can determine which replacement keyfob will work for a customer.
One other possible point of confusion about replacing ELV777K transmitters is that the available replacement remote often has an entirely different FCC ID!
This kind of situation is not that unusual for older aftermarket alarm system remotes. While replacing such parts can be a little more complicated than replacing a 3-button remote for a Ford F-150 truck, the good news is that there are still replacement remotes available.
