Abloy
The Abloy Protec2 340 Padlock represents the pinnacle of mechanical security engineering. Crafted from case-hardened steel with a chrome finish and boron steel shackle, it features a virtually unpickable disc-detainer mechanism with billions of possible key combinations. The smooth-operating internal mechanisms show no signs of wear even after years of use in harsh environments, making it the gold standard for those requiring maximum security protection.
The Abloy Protec2 340 Padlock is the ultimate 'buy it and die with it' security investment — virtually unpickable with fortress-like construction that will outlive you. However, it's a sealed unit with a fatal flaw: lose your keys, and you've likely lost your $300+ padlock. While backed by a solid 10-year warranty, the North American service desert means finding qualified locksmiths is nearly impossible. Perfect for those requiring maximum security with no compromise, but only if you're meticulous about key management.
The Abloy Protec2 padlock offers exceptional security but extremely limited repairability.
Bottom line: Designed to be tamper-proof rather than repairable - a lost key often means a discarded lock, and specialized tools/licensing make DIY servicing nearly impossible.
The Abloy Protec2 340 Padlock is the gold standard in high-security mechanical locks. The disc-detainer mechanism is virtually unpickable even by professional locksmiths, making it a true BIFL investment for those requiring maximum security.
Bottom line: This is the padlock you buy once and pass down to your children - just don't lose the keys, as replacements are expensive and difficult to source in North America.
Abloy offers a strong 10-year warranty on their Protec2 padlocks, covering defects in materials and workmanship. The company has built a reputation for exceptional security and reliability.
Bottom line: Abloy's warranty reflects their confidence in their high-security locks, matching their premium positioning with substantial long-term protection that appears to be honored consistently.
Abloy Protec2 is treated like the holy grail of padlocks in security communities, with lockpickers calling it virtually unpickable and professionals viewing it as top-tier or endgame security.
Bottom line: A community favorite for unbeatable security, but the difficulty getting keys replaced in North America keeps it from a perfect score.
