A: Look for the laser-etched "MK-N 1822" on the face of the cylinder and a holographic serial sticker on the packaging. The Final Verdict: Is the Upgrade Worth It? If you currently rely on legacy 1822 hardware, the migration to the Multikey 1822 New is inevitable. The old patent has expired in many regions, leading to cheap blank availability and increased vulnerability. The "New" generation closes every known exploit.
A: Yes. The new front housing has a sacrificial snap-line that breaks away, leaving the core locked in place even if the outer cylinder is snapped.
