Why Changing Locks
Changing locks in Paramount is one of the most reliable ways to prevent unauthorized access. Lost keys are a common issue, and once a key is missing, there is no way to know where it might end up. Replacing the lock removes that uncertainty completely.
When you move to a new house or office, previous occupants or service providers may still have keys. Even well-meaning people may have shared copies in the past. Lock Change Paramount service ensures that only you control entry from day one.
Stolen keys create an immediate risk because the lock itself is no longer secure. Waiting increases exposure and stress. A lock change eliminates the threat before it becomes a problem.
After a burglary or attempted break-in, internal lock components may be weakened. Even if the lock still turns, it may fail later under pressure. Lock replacement is often necessary for proper burglary repair.
Security upgrades are another reason many property owners replace locks. Older hardware may not meet current security expectations or may be worn from years of use. New locks improve resistance and daily reliability.
Lock Change Vs Rekey
Lock change replaces the entire lock or cylinder, giving you brand-new hardware and keys. This option is ideal when locks are damaged, outdated, or when you want higher security.
Rekeying keeps the existing lock but changes the internal pins so old keys no longer work. It is usually faster and more cost-effective when the lock body is still in good condition.
The best solution depends on the door, usage, and long-term needs. A locksmith can inspect the lock and recommend the right approach.
Deadbolt Vs Mortise
Deadbolt locks are commonly used on residential doors throughout Paramount. In a deadbolt lock, the cylinder is built outside of the door frame, and the bolt extends into the strike plate.
This design makes deadbolts easier to replace and upgrade. They are available in standard and high-security options and are suitable for most homes.
Mortise locks are installed into a pocket cut inside the door. They combine the latch and locking mechanism into one solid unit.
Mortise locks are designed for durability and frequent use, making them common on commercial doors and storefronts. They handle heavier traffic and thicker doors well.
Selecting the correct lock type improves performance and extends the life of your door hardware.
Smart Locks
Smart locks allow access using codes, apps, or credentials instead of physical keys. They are widely used in Paramount for rentals, offices, and busy households.
Standard smart locks replace the entire lockset and provide a clean, modern upgrade. They are ideal when replacing existing hardware.
Retrofit smart locks attach to the interior side of an existing deadbolt. This option keeps the exterior hardware unchanged while adding keyless access.
Smart locks make it easy to manage access without rekeying. Professional installation helps prevent alignment and connectivity issues.
Do It Yourself VS Using Professional Locksmith
DIY lock installation can work for basic doors with standard hardware. The main advantage is lower upfront cost.
Professional locksmith service reduces the risk of incorrect installation and door damage. Locksmiths also identify hidden issues like misalignment or worn latches.
Professional service often includes warranty on parts and labor, which DIY installation does not provide.
For long-term reliability, professional lock change service is usually the better investment.
