Hello all,

I have a problem. I have lost (never had) the keyfob of my RRC LWB 4.2i '93 (NAS). The alarm ECU is partnumber RTC7753, see photos. To find out what type of ECU I have and at what frequency it works, I took the ECU out. Even after that I couldn't figure out what frequency the system is operating on. I contacted a website (remotekey dot uk) and they said the following.

Hello Stefan
Your system was an insurance upgrade mainly for the NAS market but at $1000 extra and it was fitted by the dealers not from the factory very few were fitted so we never invested time into this system as we have ever been asked only 3 or 4 times, the UK had a conolog system upgrade which has the same problem:

The original Lucas 17VT system was fitted from the factory but not knowing who fitted the upgrade and if the Lucas connections are still fitted and then it's obtaining a Lucas 17VT control unit + fobs


Now I come from the Netherlands so it is difficult to find information about this, because it's an NAS RRC. Perhaps you can help me? Any experience with this upgraded alarm system?

Best regards

Stefan
