A jammed ring lock, a lost bike key or a frozen chain lock can leave you stuck on the street with no way home. Nova Slotenmaker provides a fast, professional bicycle lock opening service in Amsterdam and surroundings for city bikes, e-bikes, cargo bikes and scooters.
When you need a bicycle lock opening service
There are several common situations where a specialist is the safest option:
- You have lost the key to your bike or e-bike
- The lock is jammed and the key no longer turns
- A second-hand bike came without a working key
- The lock is frozen or corroded after weather exposure
- The key broke off inside the cylinder
Types of bicycle locks we open
We work with the full range of bike locks used in the Netherlands.
Ring locks (frame locks)
The classic Dutch ring lock built around the rear wheel. Common on city bikes and e-bikes.
Chain locks
Heavy chains with a separate lock body — popular for secondary security.
U-locks and folding locks
Rigid high-security locks, often with advanced cylinders.
E-bike & scooter locks
Integrated locks on e-bikes, fat bikes and small scooters.
How a professional bike lock opening works
We always try the least invasive method first. The technician inspects the lock, identifies the mechanism and chooses the right tool — picking and bypass techniques where possible, controlled cutting only when the lock cannot be opened any other way.
- On-site inspection of the lock and bike
- Damage-free opening where possible
- Controlled cutting as a last resort
- Advice on a suitable replacement lock
What affects the cost
We avoid fixed price claims because every situation is different. The cost depends on:
- Type of lock (ring lock, chain, U-lock, folding lock)
- Brand and security level of the lock
- Whether the lock can be opened damage-free or must be cut
- Location and accessibility of the bike
- Whether you also need a new lock fitted
Bike shop vs lock specialist
A bike shop can usually fit a new lock, but they often cannot open a locked bike on the spot and may refer you to a specialist anyway. A lock specialist like Nova Slotenmaker can come to your location, open the lock and advise on a stronger replacement in one visit.
Tips to avoid bike lock problems
Most lockouts are avoidable with simple habits:
- Keep a spare key at home in a fixed spot
- Lubricate ring locks with the right lock spray once a year
- Replace worn or rusty locks before they fail
- Choose ART-certified locks for better insurance cover
