Domestic Locksmith FAQs

Common questions our residential locksmiths are asked about home locks, rekeying and door security.

Should I rekey or replace my locks after moving into a new home?

In many cases, rekeying the locks is a practical option after moving into a new home. Rekeying changes the lock barrel so old keys no longer work, while keeping the existing lock hardware in place. If the locks are damaged, worn or no longer suitable, lock replacement may be the better option.

Can all the locks in my home work from one key?

Yes, in many homes it is possible to have multiple locks set up so they work from the same key. This is known as having your locks keyed alike and can make everyday access much easier, especially where you have several doors, gates or external locks around the property.

Is it better to repair a lock or replace it?

It depends on the condition of the lock and the problem you are experiencing. Some locks can be repaired or adjusted, especially if the issue is caused by wear, alignment or a minor fault. If the lock is badly damaged, unreliable or no longer secure, replacement may be the safer long-term option.

Can a locksmith unlock my house without damaging the door?

In most situations, yes. Professional locksmiths use specialised tools and techniques designed to open locks while minimising the risk of damage to the door, frame or lock hardware. The best method depends on the type of lock, the condition of the door and the circumstances involved.

When should I upgrade deadlocks or window locks?

It may be worth upgrading deadlocks and window locks if they are old, worn, difficult to use or no longer provide the level of security you need. This is particularly common after moving into a property, completing renovations or improving home security.

Can sliding glass door locks be repaired?

Yes, many sliding glass door locks can be repaired, adjusted or replaced depending on the condition of the lock and door. If the lock is sticking, not latching properly or no longer feels secure, it is worth having it checked before the problem becomes worse.

Can screen door locks and closers be replaced?

Yes. Screen door locks and closers can often be repaired or replaced if they are worn, damaged, difficult to operate or no longer closing correctly. A locksmith can identify whether the problem is with the lock, handle, closer or door alignment.

Can you repair or replace entrance lock sets?

Yes. Entrance lock sets can often be repaired, adjusted or replaced depending on the issue. If the handle is loose, the key is difficult to turn, the latch is not operating correctly or the lock no longer feels secure, it is worth having it inspected.

Can I get spare house keys cut if I only have one key?

Yes, in most cases spare keys can be cut from an existing working key. It is generally better to organise spare keys before the last key is lost or damaged. Precision key cutting can help ensure you have extra copies available when needed.

Do you service homes outside Penrith?

Yes. Our mobile residential locksmiths service Penrith, surrounding suburbs and the Blue Mountains region. If you're unsure whether your location falls within our service area, contact our team and we can confirm availability for your suburb.

"Spoke with Paul from the office who was so easy to talk with, who understood my door issues, acted without hesitation and provided me with a written quote within an hour. Best part of all was arriving home at the exact time the workman arrived, fixed the door and lock within 30 minutes and I was sorted. You have no idea how many companies I have tried contacting to get this job done and without luck until now. Well done Protech!"

Philip WoodGoogle Review

"So accommodating, polite and super fast service. Arrived 10 minutes after calling. 100% recommended!"

Amanda HumphreysGoogle Review

"Fast, reliable and professional service. After being let down by many local locksmiths, and told it couldn’t be fixed, Protech repaired our front door deadlock, with no issues. I only wish I had contacted them sooner !"
