🚗 It Depends On The Model Of Your BMW Vehicle But You Can Get Keys 50% Cheaper Then Your BMW Dealership. Get A Free Quote Now.
Depending on the vehicle, the work may involve a mechanical blade, remote-control electronics, an immobiliser transponder or a proximity smart key. Tell us the model, year, registration, location and whether another working key remains.
For the wider service, visit Car Keys Dublin or read about car-key duplication.
Compatibility note: Registration year alone does not identify a key. Generation changes, imports, factory options and previous lock or ignition work can change the correct part and programming route.
Model-specific preparation
BMW models & what to check
Examples include 1 Series, 2 Series, 3 Series, 4 Series, 5 Series. These names help identify the vehicle; they do not mean every year uses the same key or that every procedure can be completed onsite.
1 Series
Tell us the year, registration and whether the vehicle uses a blade key, remote key or push-button start. Similar-looking keys can contain different electronics.
2 Series
The key system can change between generations. A photo of the existing key and the dashboard warning helps separate a remote fault from an immobiliser issue.
3 Series
For a spare, say whether one fully working key remains. For all keys lost, include the vehicle location and proof-of-ownership details when requested.
4 Series
Imported and special-edition vehicles may not match an Irish-market vehicle of the same year. Compatibility is checked from the actual vehicle details.
5 Series
If the key opens the doors but does not start the vehicle—or starts it but the buttons fail—tell us exactly which functions still work.
X1
Do not order from the casing shape alone. Blade profile, transponder, frequency and programming route must suit the specific vehicle.
X3
Tell us the year, registration and whether the vehicle uses a blade key, remote key or push-button start. Similar-looking keys can contain different electronics.
X5
The key system can change between generations. A photo of the existing key and the dashboard warning helps separate a remote fault from an immobiliser issue.

What we can assess
BMW car-key services
Choose the service that best matches the problem, then send the vehicle details so we can confirm the correct route before booking.
01
BMW Car Key Repair
If your key has cracked or chipped, you may need it to be repaired, rather than totally replaced. Whether your key has become too worn to function properly or it has a scratch that needs fixing, our technicians can repair it onsite.
A cracked case, worn button, loose blade or damaged folding mechanism may be repairable. We first establish which functions still work so a casing problem is not confused with failed electronics.
02
BMW Car Key Duplication
If you have bought your car second hand, you may only have been given car key to start the engine. If you need a spare, we can carry out a quick car key duplication service for your BMW car keys. It’s always more advised to have a duplicate of your BMW car key, in case one of them gets broken or lost in the future.
If one working key remains, arranging a spare is generally more straightforward than waiting until every key is lost. The job may involve both blade cutting and electronic programming.
03
BMW Car Key Programming
If you have a BMW model that was manufactured after 1995, then it is highly likely that your BMW car keys will have a transponder chip. Sometimes, this can become desynchronized, and will need expert, diagnostic equipment to get it working again. We can carry out this service, right where you are.
Remote synchronisation and immobiliser programming are not automatically the same procedure. The vehicle, key and security system must be matched before programming is attempted.
04
BMW Electronic Steering Column Lock Repair
Steering column lock failure is becoming a common reason for not being able to start your BMW car. Here at Dyno Locks, we can provide you with a quick repair for your steering column lock to get you back on the road as soon as possible. Find out more about the fault here.
A steering-lock warning can involve the key, electronic lock or another vehicle-side component. Tell us the exact warning and whether a spare key produces the same symptom.
05
BMW Car Opening
If you’ve locked your keys inside your car, and need urgent access, we can provide you with a locksmith who can break into your car and retrieve them. They will leave your car in pristine condition.
If the keys are locked inside, contact us for assistance. We verify your entitlement and aim to use a non-destructive entry method appropriate to the vehicle.
06
BMW Electronic Ignition Switch Repair
As any other electronic component BMW electronic ignition switches tend to fail over the time. Here at Dyno Locks we have a solution for those situations as well. Contact us with your vehicle requirement and we’ll be happy to assist you.
Failure to respond when the key is inserted or the start button is pressed does not always mean the key itself is faulty. The symptom should be identified before parts are replaced.
07
BMW Car Lock Repair/Ignition Barrel Repair
You may find yourself having problems with your door lock or ignition barrel, which may need fixing. Our technicians use the latest equipment to effectively repair car locks and ignition barrels, at a lower cost than most garages.
A sticking key, damaged door lock or broken blade needs mechanical assessment. Stop forcing a jammed key and tell us whether a spare operates normally.
08
BMW Lost Or Broken Car Key Replacement
If you have lost or broken your BMW car keys, and you’re in need of replacement, then we can provide you with a brand new set of keys while you wait. This will mean that you don’t have to worry about the expense of towing your car to a dealer, or having to wait 10 working days. We will come to you, wherever your vehicle is located.
When no working key remains, we identify the likely key, cutting and programming requirements. Availability, timing and onsite completion depend on the individual vehicle and required parts.

Common questions
BMW replacement-key FAQs
Can Dyno Locks replace my BMW key?
Dyno Locks can assess replacement options for many supported BMW vehicles. The model, year, key system, parts availability and whether a working key remains determine the available route.
Can you make a spare while one key still works?
Where supported, this is normally the best time to arrange another key. Send a photo of the working key and the vehicle details so cutting and programming requirements can be checked.
What if every key is lost?
An all-keys-lost job is more involved than copying a working key. It can require vehicle entry, key cutting, security programming and proof that you are entitled to access the vehicle.
Can you repair a damaged remote or key case?
Sometimes. A broken shell, worn button or damaged blade is different from failed electronics or an immobiliser fault. Tell us which functions still work and keep all broken pieces.
How do I get an exact price?
Send the model, year, registration, location, the problem and clear photos. Dyno Locks provides a free, no-obligation quote and confirms the price before work begins.
