1How long does it take to get a simple key duplicated?
It is a very quick process, and our professional locksmiths should have you back on the road within 20 minutes.
2I have a key marked “Do Not Duplicate”. Can duplicate such a key?
Keys marked “Do Not Duplicate”, “Do Not Copy”, or “Unlawful to Copy” may be duplicated only if a letter of authorization from the owner or supervisor is presented with the request for duplication. If we are not already familiar with the property, and if we can't confidently confirm the keys belong where you say it does, then under the Business and Professions Code of California, Section 6980.54, the duplication of such keys is prohibited. However, if we know you are authorized to make the request (by written authorization), you would need to provide a valid photo ID, and sign a form with the necessary information required by California state law.
3Can you reprogram my car key?
Currently we can program most keys for General Motors, Ford, Dodge, Toyota, Honda, and more. However, European models such as Mercedes Benz, BMW, Jaguar, etc… can only be programmed by their respective dealers.
4What should I do if I lost my car or truck keys?
If you are the original buyer of the vehicle, you may have a key code available. A professional auto locksmith can help you determine that. Just give us a call, so we guide you.
5What is a high-security lock?
High-security locks have restricted key access, and these keys are very difficult to duplicate. They also offer the safest protection against potential burglaries, so if that is your concern, just ask us for the options.
6My key broke in the lock, what do I do?
If your key broke inside of your lock and the door is unable to open and the key is stuck in there, give us a call. We can send out our locksmith technician to remove it in no time.
7Why should I use a locksmith instead of a hardware store?
Since most hardware store employees are not licensed locksmiths, they are limited in the scope of locksmith services they can provide. Locksmiths are licensed and trained professionals in the field of lock maintenance and security.
8Do you provide commercial and residential locksmith services?
We absolutely do, and our mobile locksmith service is available 24 hours, 7 days a week!
9Will you cause any damage when opening my car door or trunk?
No. We have the best locksmiths near you, and they will use the safest methods and practices, without causing any damage to your car or truck.
10Is it important to have a licensed locksmith?
Absolutely! A locksmith’s license is required to operate a locksmith company or shop in the state of California. In order to get a license, an applicant must submit to a mandatory criminal history background check through the Department of Justice and the Federal Bureau of Investigation.
11How can I enhance the security of my home or business door?
The first step would be to make sure that the door frame is strong enough. Consult an expert and use brands that are known for their durability. Do not attempt to use new technology unless you fully understand what it entails and the possible risks of installing it. We recommend that you always go for quality!
12What does lock rekey mean and what does it include?
Lock rekey involves the replacement of the current configuration or tumbler of the door locks so that the lock will only open and lock with a new key. This ensures security when someone is moving to a new house or the room-mate moves out. Our diligent specialists in Los Angeles will make a new key to fit the lock.
