Audiovox has sold alarm systems using two different remote transmitters with FCC ID ELVNTRCA. They are both 2-way “transceivers”. One had an LCD display and used the OE part numbers 5BCR03 and 5BLCTX. The other had an LED display and used the OE part number 5BLETX. The LCD remote was used on some of Audiovox’s best-selling 2-way systems, so it is a very common part. The LED part was used less frequently.
Two-way systems are very useful and have become the standard in aftermarket alarm circles. Receiving feedback from the vehicle is very handy where both remote engine starting and theft protection are concerned. Unfortunately, LCD displays are not very durable. They break often under high impact, such as dropping on concrete.
Audiovox has discontinued production of the original LCD remote with FCC ID ELVNTRCA. Fortunately, there is still a replacement option. Audiovox’s part 5BCR07P, which has a different FCC ID – ELVATRBB, is compatible with systems that originally used the ELVNTRCA LCD remote. For more information, see the link below.
