#### **Cons:**1. **Higher Price Point** Compared to basic **Grade 2 or Grade 3 locks**, the Z661A is **more expensive**, which may be a deterrent for budget-conscious buyers.
2. **Key Duplication Challenges** While the keyway is secure, **specialized locksmiths or key-cutting services** may still be able to duplicate keys, though it requires additional effort.
3. **Installation Complexity** If you are not experienced with lock installation, fitting the **deadbolt and latch mechanism** correctly can be tricky, especially in older door frames. Professional installation is recommended.
4. **Limited Aesthetic Options** The lock comes in **standard finishes (brass, black, or stainless steel)**, with fewer decorative options compared to lower-security locks.
5. **Potential for Sticking Over Time** Like all locks, **dirt, debris, or lack of lubrication** can cause the mechanism to stick. Regular maintenance is necessary to ensure smooth operation.
6. **Not Pick-Resistant (But Highly Secure)** While it is **not designed to be pick-proof**, its **Grade 1 classification** means it is far more resistant to picking than standard locks. However, a determined burglar with the right tools could still bypass it.
