One of the largest manufacturers of aftermarket alarm systems is Nutek. Their FCC registrant code is “ELV”. You may not recognize the brand because very few of their systems are sold under the Nutek name. But you probably will recognize the brand name Audiovox. Most Audiovox systems are made by Nutek, so most of the aftermarket alarm remotes used on Audiovox systems start with the letters “ELV”.
We have not done a recent count, but there are scores of replacement remotes with FCC ID ELV…. Some have numeric characters following the registrant code, such as the older, but very common FCC IDs ELV777A and ELV777K. Even more common, are FCC IDs that have “AT”, then a number, then another letter, such as ELVAT6B, ELVAT0F, and so forth. Perhaps Audiovox (or Nutek) did not want to go to two-digit numbers after “ELVAT”, because they have more recently used FCC IDs that are all letters, such as ELVATDB, ELVATRBB and such. Audiovox has also used keyfobs with FCC IDs beginning with ELVMT — such as ELVMTHD.
There are literally scores of replacement Audiovox remotes that use FCC IDs that follow these basic patterns. So, when you are buying a replacement car remote and you search by FCC ID, you should take care to try to enter the FCC ID correctly. Of course, we are always here to help if you have any problems.
