Replace the Locks in Your Home or Office

Your office or home security should always be up to date, but the reality is that door locks are one of those items that people don't fix unless there's a real problem. Knowing there's a problem, can be difficult to determine. So how do you know there's a problem and your door locks need to be replaced or upgraded? You need new locks when:

  • You move to a new home or office - you should always change the locks when you move into a new home or office because you never know who has, or has lost, a key copy.
  • You upgrade your alarm security system - Often upgraded alarm systems aren't properly connected to the door locks, or the door locks may not match the requirements for your new alarm system. To make sure everything's connected properly, call one of our professional locksmiths. 
  • When employees leave without returning your office keys or lose their keys - this could cause a severe security breach in your office and leave you open to theft or even corporate espionage! 
  • After a break-in - burglars might disable an alarm connection or damage your locks in ways that are difficult to detect and that enable them to repeat their burglary in the future.  
  • If your door isn't closing properly - if your door doesn't close properly, chances are your locks and your alarm system are not working properly either.
  • After renovations - After all the service people leave, you should consider installing new locks on your doors and windows
  • If it's been more than 5 years since your last lock change - door lock security technology has advanced dramatically in the past few years. To make sure your home or office is up to today's security standards, call in a professional locksmith.  
  • Before an insurance assessment - If your locks are damaged, outdated or not working properly, your insurance costs will skyrocket. Call us before your insurance assessment to keep your monthly premium costs low.
  • When your key gets stuck regularly - If you have difficulty turning your key in the lock or it gets stuck, it often means your locks are damaged. Call the professionals to upgrade or change your locks.

What is the difference between a lock change and a rekey?

The difference between a lock change and a rekey is quite substantial. A lock change warrants changing out the whole lock mechanism with a new one. With a lock change, the locksmith will install all new hardware and you will have new keys. With a rekey, all that will be new will be the tumbler on the inside of the lock and the key that fits it. Many people choose to rekey the security locks to save money.

Can I have the locks changed on my car?

Yes, automobile locks can be changed over to new locks. Our professional locksmiths have changed vehicle locks for many reasons including:

  • The door locks are not working right so you must leave the vehicle unlocked. This makes it hard to leave anything in the vehicle and raises the fear that the vehicle may be stolen.
  • Someone that is no longer trusted has a key to your vehicle.
  • The door lock is damaged or removed.

If your vehicle has a chip system, it is important to note that you will have two separate keys. Because the ignition also works using the original key you will still need to use the older key to start the vehicle. The other option would be to change the door locks and the ignition lock so that two keys do not have to be kept.

Dave is great! He was punctual and professional. And after installing the new locks on all of our doors, he cleaned up after himself! The same cannot be said for the last service I hired… would definitely recommend and use again!

Adrian Stanton

We live not too far from Chicago and I spend about a hour and a half to get to my office. Mornings are always in a hurry for me and a broken door would be the worst I could expect. However, this was exactly what happened. I had no time to lose and so I called 247 Ontime Locksmiths. The expert guy from Locksmiths could fix the problem and I could go to work.

Tim Lewis

My car door didn’t open at all. Just a phone call to 24/7 Local Locksmiths and in less than 15 minutes I could drive my car again! Good job!
