Cost of Copying a Key

Duplicating a key is usually the most affordable option. In Irving, TX, the cost of copying a key typically ranges between $5 and $20 for standard house keys. More complex keys, like car transponders or high-security keys, can cost anywhere from $50 to $150.

Key duplication is quick, convenient, and ideal for spare keys. Bulldog Locksmith offers key duplication services for both residential and commercial needs.

Cost of Replacing a Key

Replacing a key can mean creating a brand-new key from scratch or replacing the entire lock system. Costs vary:

House key replacement: $10 – $50 for simple cuts
Car key replacement with programming: $100 – $350
Smart key fob replacement: $150 – $500
Full lock replacement: $100 – $250 per lock

If your key is lost and security is a concern, replacing the lock may be the best option to ensure safety.

Factors That Influence Cost

The decision between copy vs replace a key often depends on these factors:

Key type – Standard keys are cheaper to copy; smart keys are expensive to replace.
Lock system – High-security locks may require specialized duplication or full replacement.
Urgency – Emergency service can increase costs.
Security risk – If the key was lost (not just broken), replacement is often the safest choice.

When to Copy a Key

Copying is ideal when:

You want spare keys for family members.
Your current key is working but you want backups.
You have a simple lock and don’t require reprogramming.

When to Replace a Key or Lock

Replacing is better when:

You’ve lost your only key and are concerned about theft.
Your lock is old, worn, or damaged.
You moved into a new property and want full security control.

In such cases, Bulldog Locksmith provides lock repair and replacement services across Irving.

Copy vs Replace Car Keys

For vehicles, costs depend on the model:

Copying a car key: $50 – $120
Replacing a car key: $120 – $350
Smart fob replacement: $150 – $500

Modern vehicles often require programming, making replacement more expensive. Bulldog Locksmith specializes in automotive locksmith services, including fob programming.

Copy vs Replace House Keys

For residential properties, copying is usually the cheapest option unless the key is lost. Replacement is strongly recommended when moving into a new home, after a break-in, or if a roommate moves out without returning keys.

Bulldog Locksmith offers residential locksmith services in Irving.

Copy vs Replace Business Keys

For commercial properties, replacement is often safer because businesses rely on secure access. Master key systems, electronic access, and high-security locks usually require specialized service. Costs are higher, but security is critical for protecting assets.

Security Considerations

While copying is cheaper upfront, replacement ensures long-term security if a key has been lost or stolen. A lost key could allow unauthorized access, so rekeying or replacing the lock is often the safest choice.
