How We Key A BMW Safely

BMW is one make where we'll do every job at the car, all keys lost included, but the method depends on the generation.

2005 To Around 2009

Cars carrying the CAS2, CAS3 or CAS3+ module, built between about 2005 and 2009, will normally accept a new key straight through the OBD socket. They're the quickest BMW jobs we do.

After 2009, And The F-Series

Later cars, and the F-series that followed with their CAS4, FEM and BDC modules, need the module read on the bench, in a stable setup, before the key can be made. It takes longer, but it's the safe way. Some locksmiths try a shortcut on these modules to save time, and when it goes wrong it can leave the car undriveable. We don't take that risk, and we've repaired modules that others damaged trying it.

The Old Slot Key Problem

The E-series cars, such as the older 1 and 3 Series and the X5, have a key that slots into the dash to recharge.

Once it stops holding charge and the car ignores it, the key itself has given out; there's no battery to change. The cure is a new key coded to the car, made where it's parked.

The BMWs And Minis We Cover

BMW Car Key Replacement Cost

Model, generation and whether any key still works decide what you'll pay.

A spare is cheapest; a later BMW with nothing left needs bench work and runs longer. The registration gets you a fixed figure before the van moves, nothing's taken upfront, and extras are explained in advance. Bigger faults need an in-person diagnosis, with a call-out charge for tracking down the cause.

Your questions

BMW Key Questions

Can you replace a BMW key with all keys lost?

Yes, for every BMW model from 1998. Cars from about 2005 to 2009 usually code through the OBD socket, while later models and the F-series have their module bench-read first, which adds time but keeps the car safe. Bring your logbook and photo ID to the car when we meet you.

Do you cover Waterlooville for BMW keys?

Yes. BMW key replacement in Waterlooville, Havant and the surrounding area is part of our regular patch, along with Portsmouth and the rest of Hampshire. We come to the car wherever it's parked, and no dealer trip is involved. Ring with the registration and we'll book a time.

I'm outside Hampshire. Can you help?

Our work stays within Hampshire, East Dorset and South Wiltshire, since every BMW key is made at the car itself. Further away, a nearby mobile locksmith can carry out BMW car key replacement in the same way. It's worth asking how they treat the security module, because a careless shortcut can cause costly damage.

Transit Custom Ignition Repair.

"I cannot recommend Alec enough. My transit custom lock was not turning. I did not know Alec at this point and called another locksmith. To cut a long story short the other locksmith attempted a repair and then gave up, leaving me with a van I could no longer use. I called Alec who came out next day; he repaired the damage done by the other locksmith and custom made a replacement ignition barrel so one key still does the doors and the new ignition. I couldn't be more pleased. Price was very fair too!"

Can work on most cars! Pricing is very reasonable! Fast reliable service!

"Absolutely spot on! After ringing about 15 different companies who said they couldn't help and one company even saying the series of my car doesn't exist I found smarttech who I contacted who could finally help! The next day he came out and I now have access and a new key to my car! Fast and efficient polite service! Highly recommend!!"
