The 2013–2015 X1 uses the same key setup, so everything on this page applies to those years too. The full picture is on the BMW X1 key guide.

2015 BMW X1: key facts

Key type: Smart / proximity key
Push-to-start: Yes
Transponder chip: ID46 (PCF7945, Hitag2)
Programming: OBD
All keys lost: We can originate new keys on site

Slot-key car without Comfort Access on most US trims: the KR55WK49127-family ID46 fob inserts into the dash slot. Add-a-key and all-keys-lost are documented OBD procedures for E-series CAS3/CAS3+ (Abrites BN014/BN016). One locksmith marketing page calls the 2013-2015 X1 'EWS4 with ID44' — the catalog fitment contradicts that; we confirm by VIN.

Same key system as the 2013–2015 X1

BMW kept the X1's key system unchanged across 2013–2015, so everything about replacing a 2015 key — blanks, programming, and what happens if every key is lost — matches the rest of that run. The full year-by-year breakdown lives in our BMW X1 key guide.

What drives the price is the key type, whether you still have a working key, and where the car is parked. There's more on BMW programming in general on our BMW key page.
