Best Alarm Padlock UK

A padlock is a good thing to have as it can help you secure a lot of doors – the garage door, the garden door, the one on the shed in the back of the garden, and even things like motorcycles and bikes. But if you live in a noisy neighbourhood, a simple padlock might not be enough.

For example, if your garage is protected by a simple padlock and you hear some noise one night, without knowing its cause, you may start to wonder if someone broke into your garage. Eventually, you’ll either have a hard time falling asleep or go assess the situation.

Such situations can be avoided with the help of a padlock with built-in alarm. If your padlock gets broken or damaged, an alarm will let you know that it is your garage indeed that is getting robbed!

Best Alarm Padlock – Buying Guide

You shouldn’t expect buying a padlock with a built-in alarm to be easy. Why? Because, first of all, they are still not that popular – not many people know that padlocks with alarms are actually a thing and that are reliable as well.

Probably most of us, when thinking of alarm padlocks, imagine some flimsy locks that are better at letting you know that the lock has been broken rather than being sturdy enough to prevent themselves from being broken.

With some locks, the former does apply and this is why you need this comprehensive buying guide on how to buy the best alarm padlock available!

Things to Consider when Buying an Alarm Padlock

Materials

Proper padlocks are made of heavy-duty materials that can stand electric saws, immense pressure and so on. As you’ve seen with most of the products showcase above, all padlocks are made of strong metal with shackles made of alloy steel, which is the best material in this case.

Anything that is not a heavy-duty metal will not protect your assets if someone comes equipped and determined enough to break your lock.

Design

When it comes to the design of alarm padlocks, you must consider where the alarm speaker is placed and how easy it is to muffle or damage it. A proper padlock alarm system has its speaker on the top of the lock, under the shackle, meaning that while it is locked onto something, the thief can’t cover the speaker.

Some models come with speakers on the side or the bottom of the lock. Make sure that, if covered, the alarm can’t be muffled and, most important, that the speaker can’t be damaged if you insert something sharp through the speaker’s holes.

Locking Mechanism/Un-locking Mechanism

Most padlocks are locked and unlocked via the classic key. However, some models on the market come with a 4-digit password system or with a remote that allows for easy locking and unlocking.

While the choice depends on personal preference, keep in mind that your key will always fit your lock, whereas digit password systems and remotes can easily malfunction and leave you dealing with a continuously beeping alarm.

We would recommend you to choose a classic, key-operated, padlock.

Alarm Power

A high-security padlock with alarm of under 100dB should not be considered as, at that power level, they can be easily muffled and ignored even by trespassers. Ideally, alarms of over 105dB can be easily heard if you use the lock on your garage door or a motorcycle parked in front of your home.

At the same time, 105dB+ makes for a not so common sound that would come from the direction of a bike or garage door, alerting citizens and passers-by as well.

Check if the alarm is not covered by the padlock too much that it would muffle it. Even if the alarm is advertised as powerful, the design of the padlock may limit its power.

Alarm Module Protection

As mentioned above, you shouldn’t be able to tamper with the alarm in any way – because if you can, so can a thief. On top of that, the alarm should activate when the battery compartment is tampered with as well.

However, speaking of alarm module protection, we refer to the alarm module being both water and dust-proof, as these two elements can kill an alarm system. If they’re not going to kill the alarm, they will surely damage the speaker and the alarm power/quality as well.

Additional Accessories

Naturally, a heavy-duty siren alarm padlock should come with at least 2 spare keys and 2 sets of spare batteries. The last thing you want to happen is another family member having the only pair of keys with them or the batteries failing right before leaving for holiday.

If you buy an alarm padlock that can be used as a disc brake for your motorcycle as well, make sure it comes with a reminder cable in a bright colour as well. Since you don’t want to damage your motorcycle brake system, a brightly-coloured reminder cable will let you know that, before starting the engine, you should remove the alarm padlock.

FAQ – Frequently Asked Questions

Q: How to test my alarm padlock?

Each manufacturer will specify the conditions that have to be met for the alarm to activate. However, most alarm padlocks require only sudden vibration or movement to activate the alarm.

As such, simply fasten the lock onto the garage door or bike and give it a strong wiggle. If the alarm turns on, then it works perfectly. If you want an extra layer of security, purchase a lock with an alarm that activates when the wire/shackle is cut or when anything else but a key is used to unlock it.

Q: How much do alarm padlock batteries last?

Even though this depends on the alarm’s brand/manufacturer, as well as on those of the batteries, they are known to last around 3 to 6 months under average use.

For example, a padlock alarm lock meant to secure the garage door overnight might last around 3 to 4 months in terms of alarm battery. On the other hand, an alarm padlock meant to secure a motorcycle used a couple of times a week and left idle throughout the city might last a bit longer as the alarm doesn’t stay active too much.

Q: What are the recommended temperatures for an alarm padlock?

Usually, you shouldn’t expose alarm padlocks to extreme temperatures for too long. When we say extreme, we refer to maximum -10 degrees and 60-degrees Celsius. Anything below/above these temperatures is likely to damage the alarm circuitry or the shackle.

Final Thoughts

A heavy-duty alarm padlock adds a layer of security to some of our most important belongings – namely the garage or the bike/motorcycle. While a regular lock won’t stop thieves from further thieving, so to speak, an alarm padlock will scare them away even if they manage to break the lock.

As such, if you have a fancy motorcycle or a nice car in the garage, an alarm padlock is worth the investment, especially given that some products out there are more reliable and resilient than simple heavy-duty locks on the market!
