Advice for Schools Buying Padlocks for Lockers

We supply padlocks to schools, colleges and universities across the UK and internationally. Over the years, we have gone from simply supplying padlocks to working closely with manufacturers to develop locks specifically designed for school environments. Schools have unique requirements: hundreds of lockers, high daily usage, lost keys, code resets and the need for staff access without damaging lockers. The right padlock makes daily management easier and reduces replacement costs.

The Importance of a Master Key System

A master key allows authorised staff to open any padlock without needing the original key or code. This is essential for:

• Gaining access in an emergency

• Avoiding cutting off padlocks when keys are lost

• Reissuing padlocks to new students each term

Historically, schools could issue padlocks that students could set their own code, but staff could not reset the code for re-use. Working with British manufacturer Shield, a school-specific combination padlock was developed that allows:

• Students to set their own code

• Staff to open any lock with a master key

• Staff to reset the code so the same padlock can be reissued

This significantly reduces waste and ongoing replacement costs.

Security and Reliability Considerations

Many padlocks marketed for lockers are not designed for heavy daily use. Cheap imports often fail, seize, or are easily bypassed. Schools require padlocks with:

• Strong internal mechanisms

• Tamper-resistant designs

• High variation in key differs

Keyed Padlocks: Key Variations Matter

When supplying multiple keyed padlocks, the key variations (differs) need to be high. Some low-cost padlocks may only have around 30 key variations in total, meaning multiple students may end up with keys that open each other’s lockers. We only supply padlocks that meet a minimum of 250 differs as a starting point, ensuring security and privacy.

Combination Padlocks: Avoid Code Cracking

Many low-cost combination locks can be “felt” or manipulated to reveal the code. School students are quick to learn these techniques. The combination padlocks we supply have anti-crack mechanisms that prevent this and stand up to daily use in busy locker rooms.

Recommended Options for Schools

Combination Padlocks with Master Key Reset

Ideal for large student groups who may misplace keys but need individual access.

Keyed Padlocks with High Differ Variation

Suitable for schools where keys are issued and controlled centrally.

Both options can be supplied in bulk, keyed alike sets, or managed with master key access depending on how your school operates.

Summary

Choosing padlocks for school lockers is not just about price. Durability, student-proof security features, and staff access controls make the difference between a smooth-running locker system and a constant cycle of replacements. We test and supply only models proven to withstand busy school use.
