Spare key vs All Keys Lost

The band £170–£330 is a spare key guide: you still have at least one working BMW 1 Series key. All Keys Lost (every key gone) needs extra security steps and is quoted individually after we read your registration.

Typical on-site time for a spare key is 45–60 minutes. We confirm blanks, frequency and any online tokens before work starts.

Key families on this model: Smart.

What is specific to the BMW 1 Series

E87 uses CAS; F20 (2011–2019) is FEM/BDC; F40 (2019–) is BDC2 comfort access. The 1 Series is a frequent All Keys Lost job because it is often a second car with one key left in a coat. CAS cars we recover on the drive; FEM/BDC All Keys Lost needs a data session and a quoted price.

The emergency start slot on F20s is in the cupholder; on F40s the fob sits in a tray. Dead fob battery is not All Keys Lost — we replace the cell, confirm the car starts, then cut a proper spare.
