If you are renting a property and discover that your keys are restricted — meaning no key blanks are available on the open market — you may find it frustrating when you need extra duplicates. This is a common situation in Singapore, as many properties use branded high-security systems such as EVVA, DOM, Winkhaus, Vachette, ASSA Abloy, Miwa, TrioVing, Keso, Tesa, GEGE and others. These systems are designed for security, but they also mean only the original installer or brand dealer can provide new keys.
For tenants, this can be inconvenient because:
- You may not know who the original installer is.
- Building management may not approve additional keys.
- You may only be staying for a limited period of time.
A Practical Tenant-Friendly Solution
One option is to temporarily change the cylinder lock while you are still renting. Most modern properties in Singapore use Euro profile cylinders, which are very easy to replace. All it usually takes is removing a single screw with a common Phillips (cross-head) screwdriver, sliding out the old cylinder, and fitting in a new one.
When you eventually return the property, simply reinstall the original cylinder so everything is back as before. This way, you can have as many duplicates of your temporary lock as you need during your tenancy, without affecting the landlord’s security system.
