How many keys are typically received with high/medium security locks and cylinders?

High and medium security locks and cylinders are designed to provide enhanced security features. Typically, these locks come with three keys to ensure that users have adequate access while also maintaining control over key distribution. This allows for key management practices that can prevent unauthorized duplication.

The three keys standard ensures that there are enough for primary users, while also allowing for situations where a key may be lost or damaged without compromising access entirely. This approach balances security with practicality, making it a common practice for such locking mechanisms.
