Superglue got poured into the cylinder — can an expensive lock still be saved?

The client's name has been changed.

Let's call the client Michael. In the morning he found that his key no longer fit into the high-quality cylinder. On inspection, it became clear: glue had gotten inside.

The question came up:

"Does the expensive cylinder definitely have to be thrown away now?"

Not always — much depends on how severe the damage is.

Rule one — don't try to force the key in

If there's hardened glue inside, forcing the key in can:

• damage the key;
• deform the internal components;
• push the contamination in deeper.

Is it worth pouring in a solvent

Not without a consultation. The wrong chemical can damage:

• the door's finish;
• plastic parts;
• seals;
• the cylinder's internal materials.

If the door is currently open

This is the best-case scenario. Don't close it before diagnosis. With the door open, it's much easier to:

• remove the cylinder the normal way;
• assess the damage;
• determine whether repair is possible.

If the door is closed

The situation is significantly harder, because access has to be restored first. That's exactly why it's not worth making things worse with DIY experiments.

Should you install a keyless system after vandalism

That's one possible option, not an automatic answer. It's worth weighing:

• the cost;
• the convenience;
• backup access;
• the specific risk to the property.

For repeated vandalism, video surveillance can also help, with privacy and legal requirements taken into account.
