All drivers told not to ignore this warning light that commonly appears in winter

Soon, experts warned drivers about a dashboard key fob warning light this winter, noting it signals a key-access fault unrelated to engine or tyre issues.
Battery depletion is the most common trigger of key fob faults, while RAC noted physical damage, water submersion, and radio interference also cause issues needing specialist attention.
A full key fob replacement can cost from £250 to over £1000, with local garages and tech shops offering repairs; a new battery typically costs between £5 and £10, RAC advises.
Ignoring the light risks being locked out or unable to start in cold weather, so drivers should act quickly and use a spare key set or alternate unlocking methods if needed.
Published via a USA Today partnership, the report draws on RAC guidance, which says most key fobs last many years though older key fobs may suffer radio interference.
