The BMW Main Dealer Nightmare Avoided
BMW dealerships famously require car owners to order replacement keys from Munich, costing £420 – £600+, wait 2 to 3 weeks, and then pay an additional £150+ in "workshop diagnostic coding fees" while your vehicle sits in their lot. With The Grantham Car Key Co., we provide dedicated workshop diagnostic programming with doorstep collection & return and hand you a fully working, tested BMW smart key!
