What’s the best high security lock? – Medeco vs Mul-t-Lock

June 27, 2023

The need for High-Security locks is quite pressing. We are not talking about the threat of break-ins and violent forced entries. That is also quite problematic. What we are talking about is the ease with which locks can be picked by even amateurs. It is estimated that 35% of door entries will show no signs of forced entries. This is a problem, especially when dealing with insurance claims, where companies need to see at least some signs of forced entry.   Lock picking remains a serious challenge, but an even bigger challenge is lock bumping . Lock bumping can be easily learnt from many resources and sets of bump keys (also known as 999 keys) can be purchased easily from the internet. 

Another overlooked issue is the threat of unauthorized key duplication. For example, it could be the tenant that is renting your basement, or some other friend or acquaintance. All they need is a bare-minimum expenditure for having multiple key duplications which you don’t know about at all! Even your own set of copied keys can be easily compromised if you aren’t careful.

The point is that even amateurs, and non-professional crooks can gain entry quietly into your homes and it is imperative for you to do everything in your power to protect your homes. This is especially true given the desperate situation that COVID-19 has put everyone in. Rioters that are looting shops can very easily start to break into houses. This is where high security locks come in to play!

High-Security Locks are those that provide the best resistance to any unneeded tampering with your locks. For any lock to be considered high security, it needs to undergo the right scrutiny and be given the right security rating. This ranges from Grade 1 (highest rating) to Grade 3 (lowest rating). 

Also, as opposed to many myths surrounding them, even high-security locks are not 100% break-in-proof! But they make it almost impossible for your average person doing the break-in to succeed in what they are doing. High-security locks, therefore, need to be chosen carefully to make sure that they truly live up to their name. In commercial settings, high-security locks will be worth the extra price for example. 

We are comparing 2 of the most important brands in the high-security locks industry. We have chosen them due to their sheer presence in either the US (Medeco) and international (Mul-t-lock) high-security lock markets.

  • Medeco 
  • Mul-T-lock

Both brands of high-security locks are very popular. According to various sources, Medeco locks are used in at least 60-75% of the US High-Security market. They have been promoted by the company as the “lock that cannot be picked”. 

Mul-T-lock has also been in the business of high-security locks for close to 5 decades. The Mul-T-Lock website shows that they have a presence in 80 countries and 20,000 service centres. They are very dominant in the international market. They are an Israeli company that has a proud tradition stemming from the IDF and a signature trademark with a man with muscular arms morphing out of a key high-security lock key. It is hard to miss! 

Both companies are owned by the ASSA Abloy group, which is a Swedish conglomerate. 

They both use a similar and familiar locking system, the pin-tumbler design with springs. This is not too different from most locks that you are familiar with. Hence, it will be generally easier for your local locksmith to install either of these 2 brands on your door lock.                              

Now, for the differences. Both lock systems are quite similar and both companies have great products, but there are certain strengths and failures that each of these lock systems have which give one brand a clear advantage over the other. 

Hence, if you are looking for prevention from brute force break-ins, then consider the Medeco Maxum

Key Control: Medeco has utilized their exclusive use of angled cuts on their keys, and slider combinations to produce millions of key combinations. They have also patented a key control system that makes it virtually impossible to get a copy without your permission. In the case of Mul-T-Lock, an a magnetic strip order card needs to be presented at an authorized dealer for key duplication. Now, Medeco gives you control over duplication, but Mul-T-Lock goes a step further and makes it more rigorous to get a key duplicated. You have the highest level of key control.

Hence, if you are looking for strict key duplication controls, go for Mul-T-Lock. 

The most critical test for any high-security lock is lock picking or bumping. You need to be as secure as you can against any lock-picking or lock-bumping incidents. When it comes down to it, a high-security lock's inability to be picked or bumped is what, in the end, defines it as such. Unfortunately, Medeco's performance in this area wasn't all that great. It should be emphasized that neither brand is completely impenetrable, although Medeco's security has been broken. A website devoted to Medeco issues has noticed this! It demonstrates quite clearly how even the most recent M3 generation's security has been penetrated by something as easy as a paper clip, and how older versions (which are still widely used) have major weaknesses. In this case, Mul-T-Lock automatically wins because there haven't been any issues revealed and because it can withstand at least novice lock-picking techniques. 

After comparing the three main factors for high-security locks, it is safe to declare that Mul-T-Lock should be the top choice for overall security as it relates to the entire brand. Even while a robust Medeco Maxum lock makes a powerful statement, it is only one product within the entire company, and forced entrance break-ins are more frequent than unforced entry. Medeco is a poor choice due to significant security breaches and a lack of key duplication rules. It makes sense why Mul-T-Lock is praised by local locksmiths and blogs as the best high-security lock.

Few things are more frustrating than inserting your key into a lock, turning it as usual, and suddenly feeling it snap. A broken key in a lock can instantly turn a routine task into a stressful situation. Whether it's your home, car, or office, the inability to access your property can disrupt your day and leave you scrambling for a solution. But before you start panicking or consider replacing the lock entirely, take a deep breath. There are several effective ways to remove a broken key from a lock without causing damage. This guide will walk you through the process, helping you understand why keys break, how to remove them safely, and what steps you can take to prevent this from happening in the future. How to Fix a Stiff or Hard-to-Turn Lock Why Do Keys Break in Locks? A key breaking inside a lock is usually the result of a combination of wear and tear, force, or an issue with the lock itself. Here are some common reasons why keys snap: 1. Metal Fatigue and Weakness Keys undergo stress over time. Daily use, exposure to moisture, and bending can weaken the metal, making it prone to breaking when inserted or turned in a lock. 2. Misalignment of the Lock and Key If a lock is old, rusty, or poorly maintained, the internal components may become misaligned. This forces the key to work harder than it should, increasing the likelihood of snapping. 3. Using Excessive Force Sometimes, in frustration, people turn the key too hard when it isn’t turning smoothly. Applying extra force can cause a weak or old key to break instantly. 4. Cold Weather Conditions In freezing temperatures, metal contracts, making both keys and locks more fragile. If your key was already worn down, cold weather might push it to its breaking point. 5. Debris or Dirt in the Lock Over time, locks accumulate dust, dirt, and small debris. If these particles build up inside the lock, they can create resistance, making it harder for the key to turn properly and increasing the risk of breakage. Step-by-Step Solutions to Remove a Broken Key Safely Now that we understand why keys break, let's focus on how to remove a broken key without damaging the lock. 1. Assess the Situation First Before attempting any removal, check how much of the key is visible outside the lock. If a significant portion is sticking out, your job will be much easier. If the key is deep inside, you’ll need to use more precise techniques. 2. Try Tweezers or Needle-Nose Pliers If part of the broken key is visible, use a pair of fine-tipped tweezers or needle-nose pliers to grip and gently pull it out. However, be cautious—if your tweezers are too thick, they may push the key further into the lock, making extraction more difficult. 3. Use a Broken Key Extractor Tool Professional locksmiths use a broken key extractor, a thin tool designed to slide into the lock and hook onto the broken key's teeth. If you have one, carefully insert it along the groove of the key and pull it out slowly. 4. Apply Lubrication If the key is stuck, applying a lubricant like WD-40 or graphite powder can help loosen it. Spray a small amount into the lock and wait a minute before attempting to remove the key again. 5. The Tapping Method If gravity can work in your favor, hold the lock opening downward and gently tap it against a hard surface. Sometimes, the vibration is enough to loosen the broken key and allow it to fall out. 6. Using a Jigsaw Blade or Thin Wire If you don’t have an extractor tool, a fine jigsaw blade or thin piece of stiff wire can work in a pinch. Insert it along the broken key, try to hook onto the ridges, and gently pull it out. 7. Seek Professional Help If none of these methods work or the key is deeply lodged inside the lock, calling a professional locksmith is the best option. A locksmith has specialized tools and experience to remove the key without damaging the lock. Risks Involved in DIY Key Removal While removing a broken key yourself can save time and money, there are some risks to be aware of: Pushing the Key Further In : If you’re not careful, attempts to extract the key can accidentally push it deeper into the lock, making removal more difficult. Damaging the Lock Mechanism: Using improper tools or excessive force can bend or break internal lock components, leading to more costly repairs. Leaving Key Fragments Inside: If only part of the key is removed and small fragments remain, they can cause future problems with inserting and turning a new key. Preventive Measures: Avoiding Broken Keys in the Future To ensure you never have to deal with a broken key again, follow these simple preventive measures: 1. Regularly Inspect Your Keys If your key looks worn down, has visible cracks, or feels weaker when used, consider getting a new one before it breaks. 2. Keep Locks Clean and Lubricated Dirt and debris buildup inside a lock can make it difficult to turn the key. Clean your locks occasionally and use graphite powder or WD-40 to keep them functioning smoothly. 3. Don’t Force a Stuck Key If your key isn’t turning easily, stop and check for obstructions or try lubricating the lock before applying pressure. 4. Get a Spare Key Made Having a spare key on hand ensures that if one key gets weak, you can switch to the backup instead of pushing your luck with an old, worn-out key. 5. Upgrade to a More Durable Key or Lock Consider upgrading to a sturdier key material or even a smart lock system, which eliminates the need for physical keys altogether. Conclusion: Patience and the Right Tools Make All the Difference A broken key in a lock is undoubtedly an inconvenience, but it doesn’t have to be a disaster. By using the right techniques and tools, you can safely remove a broken key without damaging the lock. The key to success? Patience and precision. And remember—prevention is always better than cure. Taking simple steps to maintain your keys and locks can save you from this frustrating situation in the future. If you ever find yourself in doubt or dealing with a deeply lodged key, don’t hesitate to call a professional locksmith for assistance. With the right knowledge and approach, you can tackle a broken key issue with confidence and get back to your day hassle-free!
