Why a Replacement Key for Sentry 1170 is Necessary
I’ve found that having a replacement key for my Sentry 1170 safe is absolutely essential. In my experience, losing the original key can happen when you least expect it—whether it’s misplaced during a move or accidentally dropped somewhere. Without the key, accessing important documents or valuables becomes a stressful and time-consuming ordeal. Having a replacement key on hand gave me peace of mind, knowing I wouldn’t be locked out in an emergency.
Additionally, even if the lock mechanism wears down over time, a replacement key can often provide a smoother, more reliable way to open the safe. For me, this meant avoiding costly locksmith services or the risk of damaging the safe trying to force it open. Overall, securing a replacement key felt like a simple step that saved me a lot of frustration and protected my valuables effectively.
My Buying Guides on Replacement Key For Sentry 1170
When I needed a replacement key for my Sentry 1170 safe, I quickly realized that not all replacement keys are created equal. To help you avoid the frustration I experienced, I’ve put together this guide based on my personal journey. Here’s what you should keep in mind before making a purchase.
1. Confirm Your Safe Model
First and foremost, make sure your safe is indeed a Sentry 1170 model. This safe has a specific lock and key design, so a key meant for another model won’t work. Check the serial number or any documentation you have to confirm the model. I found this saved me from ordering the wrong key.
2. Identify the Correct Key Type
The Sentry 1170 typically uses a tubular key or a flat key depending on the version. When I ordered my key, I had to verify the exact type by comparing my original key or consulting the manual. If you don’t have the original key, contacting Sentry’s customer service with your safe’s serial number can help clarify.
3. Choose Between OEM and Aftermarket Keys
I had the option to buy an original equipment manufacturer (OEM) key or an aftermarket replacement. OEM keys are guaranteed to fit perfectly but often cost more. Aftermarket keys are less expensive but might not be as precise. I chose an OEM key for peace of mind, especially since the safe holds important documents.
4. Verify the Seller’s Reputation
Since replacement keys are security-related, I only purchased from reputable sellers or directly from Sentry. Reading reviews and checking ratings helped me avoid unreliable sources. If you go through third-party sellers, ensure they have a clear return policy in case the key doesn’t work.
5. Consider Additional Security Measures
While buying my replacement key, I also took the opportunity to upgrade my safe’s security by changing the lock mechanism. If you’re in a similar position, you might want to consult a locksmith or Sentry’s support to explore options beyond just replacing the key.
6. Prepare Proof of Ownership
To prevent unauthorized key duplication, Sentry and many sellers require proof of ownership before sending a replacement key. I prepared my purchase receipt and ID ahead of time to speed up the process.
7. Understand the Delivery and Turnaround Time
Depending on where you order from, replacement keys can take several days to weeks to arrive. I made sure to order mine well before I needed access to the safe. If you’re in a hurry, check if expedited shipping is available.
Final Thoughts
Replacing a key for the Sentry 1170 safe isn’t complicated if you know what to look for. Confirm your model, pick the right key type, buy from trusted sources, and have your proof of ownership ready. Following these steps made the process smooth for me, and I hope it helps you too!
