Lucas remote key fob frequency codes MHZ
The Lucas key fob began in 1994 and is still on sale today.
It was produced in 2 X main MHZ (megahertz) frequency’s.
433mhz and 315mhz
The below is very important:
– as you will require the correct MHZ for your vehicle.
UK Europe is mainly 433MHZ
For the rest of the world should be 315MHZ
BUT this is not always true as many vehicles have been exported and re-imported.
Many vehicles re-imported to the UK from Japan are 315MHZ
Australia and New Zealand can be both 433MHZ and 315MHZ.
Key fobs with a CE WPT 1340 LICENCE EXEMPT is Euro / UK 433MHZ
Key fobs with FCC Canada is 315MHZ
