Keyfob Won't Lock Doors
I have a 2006 Honda Accord 4 Door Sedan. I went outside earlier and noticed that my keyfob will not lock and beep the horn. The red LED flashes on the keyfob but it won't lock and arm the security system. I can unlock and open the trunk with the keyfob but cannot lock the car. I tried the spare keyfob and got the same results. Any Ideas? Thanks,

It may be a problem with the Multiplex Integrated Control Unit (MICU), which is built into the under-dash fuse/relay box.
1. Do a battery cable reset by disconnecting the negative and positive cables and connecting them together with a jumper wire for 15 minutes. -- Do not touch the battery terminals.
2. If that doesn't work, the MICU may need replacement.
