Why is my Honda CR-V not flashing lights when locking? UK troubleshooting guide

If your Honda CR-V's lights aren't flashing when locking, it's typically due to issues with door/hatch sensors, key fob battery, signal interference, or alarm system faults. In the UK, common causes include: 1) Boot or bonnet not properly closed - check both are securely shut; 2) Door ajar - verify all doors including the tailgate are fully closed; 3) Weak key fob battery - replace CR2032 battery (common in UK models); 4) Signal interference - move away from strong radio sources; 5) Failed lock confirmation - ensure all access points are secured; 6) Alarm system fault - requires Honda dealer diagnostics; 7) Wiring/relay issues - check fuse box (typically passenger side footwell in UK CR-Vs). For UK owners, first try the simple fixes before visiting a Honda specialist like Hendy or Stoneacre. Note that some UK-spec CR-Vs have different alarm configurations than international models.
