1. Identify the lock type and model
Before requesting quotes, identify the type of lock you need to replace: interior door, armored door, aluminum, or cabinet. Each type has different pricing, from 60 € for cabinets to 300 € for armored doors. Take a photo of the current lock to help the locksmith assess the job.

4. Compare prices and services offered
Analyze quotes considering not just the final price but also response time, material quality, and warranty. A standard quote ranges between 150 € and 220 €. Check if it includes removal of the old lock and what types of locks they offer (security, smart, etc.).
What can change your final price
Even similar projects can end with different budgets. These are the factors that most often push costs up or down.
Lock Type
Security locks, smart locks, or double cylinder systems cost significantly more than standard locks. A reinforced security lock can double or triple the price compared to a standard model.
Material and Quality of the Cylinder
The cylinder is the most critical component affecting price. A security cylinder with anti-picking or anti-drill protection costs between 40 € and 150 €, while a standard one ranges from 15 € to 40 €.
Time of Service
If the service is performed outside business hours (evenings, weekends, or holidays), an emergency surcharge is applied that can increase the total cost by 50% to 100% compared to the standard rate.
Door Type and Complexity
Armored doors, special doors, or those requiring additional fitting and frame adjustment work increase labor costs. A standard door is quicker to service than a security door.

This is the most common lock model in homes. The central piece of the mechanism is a cylinder with a pear-shaped or round pin, which is the space where you insert the key to open and close.
The average cost of changing this type of lock could be around 30 €, since the range of qualities and features is very wide, so you can find very simple locks starting from 15 € and security locks exceeding 50 €.
There are many types of locks on the market. If you're changing an exterior door lock, you must make sure that the model you choose is appropriate for your door type. In this regard, one of the most important things to check is ensuring that the lock closes in the same direction as the door. There are locks that close to the right and others to the left, and there are even some models that can be installed on any type of door since they close both ways.
Choose a security lock
If the time has come to change the lock on your main entrance door, it's advisable to make a good investment and buy a security lock. "Bumping" is the most common method used by thieves to enter homes. This method involves inserting a manipulated key and hitting it repeatedly until the gears rotate. To make things more difficult for criminals, it's advisable to opt for security and anti-bumping locks.
