Whether it’s due to a lost key, the need for enhanced security, or simply a desire to update the look of your property, changing a lock is a relatively straightforward process. However, like any DIY project, it’s important to have a clear understanding of how long it might take to change a lock, so you can plan your time accordingly. In this blog post, we will explore the average time it takes to change a lock, along with some factors that may contribute to varying time estimates.

1. Assessing the Lock and Tools Preparation

Before embarking on the actual lock-changing process, it’s essential to assess the lock and gather the necessary tools. This preliminary step is crucial to ensure a smooth and efficient lock replacement. On average, this initial assessment and tool preparation can take around 15 to 20 minutes. This time frame may increase if you encounter any complications or if you are unfamiliar with the specific lock model.

2. Removing the Old Lock

The next step in changing a lock is removing the old one. This process typically involves unscrewing or removing any screws, bolts, or latch plates holding the lock in place. The average time to remove an old lock ranges from 10 to 15 minutes. However, if the lock is rusted, damaged, or has any other complications, it could add an additional 5 to 10 minutes.

3. Choosing and Fitting the New Lock

Choosing a new lock that suits your specific needs and preferences is an important step in the lock-changing process. This involves considering factors such as security levels, key types, and lock styles. The time required for this step varies significantly depending on individual decision-making and research. On average, it may take 15 to 25 minutes to choose and purchase a new lock.

Once you have the new lock, fitting it into the door is the next crucial step. This process generally involves aligning the lock cylinder with the latch mechanism and securing it with screws or bolts. The average time it takes to fit a new lock ranges from 10 to 15 minutes. However, if any adjustments or modifications are necessary to ensure a perfect fit, it could add an additional 5 to 10 minutes to the process.

4. Testing and Ensuring Proper Lock Functionality

Once the lock has been installed, it’s important to test its functionality to ensure it operates smoothly and provides adequate security. Testing involves turning the key, locking and unlocking the door, and checking the alignment of the latch. On average, this testing and adjustment process can take approximately 10 minutes. However, if any issues arise during the testing phase, such as sticking keys or misaligned latches, it may require an additional 5 to 10 minutes to address those problems.

5. Making Duplicate Keys

Finally, after successfully changing the lock and ensuring its proper functionality, it’s advisable to make duplicate keys for convenience and emergency purposes. The time required for making duplicate keys highly depends on the key duplication method chosen. If you have access to a key cutting machine or visit a locksmith, it could take around 5 to 10 minutes per key. However, other methods, such as visiting a hardware store or ordering online, may involve additional waiting time.


Changing a lock can be completed within a few hours, depending on various factors. The average time estimates provided in this blog post give a general idea of the length of each step involved in the process. However, it’s important to remember that unexpected complications or personal proficiency levels can influence the actual time required to change a lock. If you lack the necessary skills or are unsure about the process, it’s always wise to seek professional help from a locksmith to ensure a reliable and efficient lock replacement.
