Trigger locks are a simple and important safety device for gun owners. They help prevent accidental discharge and keep firearms secure from unauthorized use. If you’re considering buying a trigger lock, you probably want to know how much they cost, what affects the price, and whether paying more gives you extra safety.
This article will guide you through all the key points about trigger lock pricing, types, and real-world examples so you can make a confident, well-informed decision.
What Is A Trigger Lock And Why Does It Matter?
A trigger lock is a device that attaches to the trigger area of a gun. Its main purpose is to block the trigger so the gun cannot be fired unless the lock is removed. It’s a basic safety tool but can make a big difference, especially in homes with children or visitors.
Many states in the US recommend or require gun owners to use trigger locks or other safety devices. Even where it’s not required, using a trigger lock can help prevent tragic accidents or theft. While trigger locks are not foolproof, they do add an extra layer of protection.
Typical Price Range For Trigger Locks
Trigger locks are usually not expensive. The average price for a standard trigger lock is between $8 and $25. However, prices can go much higher or lower depending on the type, brand, features, and materials.
Here’s a quick overview of common price ranges:
| Type | Low Price | High Price | Average Price |
|---|---|---|---|
| Basic Key Lock | $7 | $18 | $12 |
| Combination Lock | $12 | $25 | $18 |
| Biometric Lock | $60 | $180 | $110 |
| Heavy Duty/Custom | $30 | $80 | $50 |
As you can see, basic key locks are the most affordable, while biometric trigger locks are the most expensive.

Main Factors That Affect Trigger Lock Prices
Several things can change the price of a trigger lock. Knowing these factors helps you understand why some cost more and what you are paying for.
Type Of Lock Mechanism
- Key locks: These are the simplest and cheapest. You unlock them with a small key, similar to a padlock. Good for basic safety.
- Combination locks: These use a code or dial. They are a bit more expensive and avoid the risk of losing a key.
- Biometric locks: These use fingerprint technology. They are much pricier but offer fast access and more security.
Materials And Build Quality
- Metal locks: Stronger and longer-lasting, usually cost more.
- Plastic locks: Cheaper but can be less secure and easier to break.
Brand And Certification
- Well-known brands like Master Lock or Remington charge more for reliability and trust.
- Locks with safety certifications (like CA DOJ approval) may be pricier due to testing and quality.
Extra Features
- Some trigger locks have anti-tamper alarms, weatherproofing, or special coatings.
- Others may fit only certain models or types of guns, which can affect the cost.
Place Of Purchase
- Buying online can be cheaper due to discounts.
- Buying from a local gun store may be more expensive but offers advice and support.
Comparing Popular Trigger Lock Models
To give you a clearer picture, let’s look at some popular trigger locks and how their prices compare. This includes both basic and advanced options.
| Model | Type | Material | Price | Special Features |

This table helps you see how price, materials, and features relate. Biometric locks cost much more, but standard key and combination locks are affordable and easy to find.
Is It Worth Paying More For Premium Trigger Locks?
Many buyers wonder if expensive trigger locks are truly safer. The answer depends on your needs and how you use your gun.
- Premium locks (like biometric models) are useful if you need fast access but still want strong security. For example, police officers or people with multiple guns may prefer these.
- Basic locks work well for simple home storage or when you rarely use your gun.
- Certified locks may be required in some states or for insurance purposes.
A non-obvious insight: Even expensive trigger locks are not completely theft-proof. They slow down unauthorized access, but determined thieves can break most locks with tools. For true security, use a gun safe alongside a trigger lock.
Real-world Price Examples From Online Stores
To give you a practical idea, here are some recent prices from major online retailers:
- Amazon: Master Lock Keyed Trigger Lock, $10.99; Remington Combination Lock, $17.95; Identilock Biometric, $169.99.
- Walmart: FSDC Keyed Gun Lock, $8.97; Allen Combination Lock, $14.88.
- Cabela’s: Heavy Duty Keyed Lock, $24.99; Biometric Lock, $185.
Prices can change due to sales, shipping, or local taxes. Buying in bulk or as part of a gun safety kit can sometimes lower the price per lock.

Trigger Lock Costs: Hidden Expenses And Mistakes To Avoid
When buying a trigger lock, most people focus only on the purchase price. However, there are some hidden costs and common mistakes:
- Lost keys: With key locks, losing the key can mean buying a new lock or paying for a locksmith.
- Battery replacement: Biometric locks often need batteries. This adds a small annual cost.
- Fit problems: Not all trigger locks fit every gun. Buying the wrong size can waste money.
- Cheap materials: Some low-priced locks break easily, so you may have to buy replacements.
A second non-obvious insight: Some insurance companies offer discounts if you use certified trigger locks, which can save money over time. Always check with your provider.
How Trigger Lock Prices Compare To Other Gun Safety Devices
Trigger locks are just one option for gun safety. Let’s compare their prices to other devices:
| Device | Typical Price Range | Security Level | Ease of Use |
|---|---|---|---|
| Trigger Lock | $8–$25 | Basic | Easy |
| Cable Lock | $10–$35 | Medium | Easy |
| Gun Safe | $100–$1200 | High | Moderate |
| Lock Box | $30–$150 | Medium | Easy |
| Biometric Safe | $200–$600 | High | Easy |
This comparison shows that trigger locks are the cheapest way to add safety, but they offer only basic protection. For more security, consider combining devices.
How To Choose The Right Trigger Lock For Your Budget
Choosing a trigger lock is not just about price. Here are the key steps to make a smart choice:
- Decide your needs: Is the lock for home storage, travel, or quick access?
- Set your budget: Most people spend $10–$20, but advanced locks can cost $100+.
- Check compatibility: Make sure the lock fits your gun model.
- Look for certifications: CA DOJ or similar certifications mean better quality.
- Compare brands: Read reviews and check warranty policies.
- Think about access: If losing keys is a problem, consider a combination or biometric lock.
- Consider long-term value: Spending a bit more for quality may save money over time.
Avoid the mistake of buying the cheapest lock without checking reviews or fit. Poor-quality locks can fail and risk safety.
Where To Buy Trigger Locks And What To Expect
Trigger locks are easy to find both online and in stores. Here are common places to buy:
- Online retailers: Amazon, Walmart, Cabela’s, GunBroker
- Gun stores: Local gun shops offer advice and show fit

Most stores offer trigger locks in packs or bundles, which can save money if you have multiple guns.

Are Trigger Locks Required By Law?
Laws about trigger locks vary by state and country. In some US states, you must use a trigger lock or other safety device when storing guns, especially if children are present. Some states require gun stores to include a trigger lock with every firearm sale.
For example:
- California: Requires approved safety devices for all gun sales.
- Massachusetts: Guns must be stored with a lock if not in use.
- Canada: Trigger locks are strongly recommended for home storage.
Always check your local laws before buying. Fines for not using a lock can be high, and in some cases, insurance may not cover accidents without proper safety devices. For more details on laws and regulations, you can visit Wikipedia.
