What Interlock Stands Behind

Our promise is simple.

We do not just sell you a digital lock. We help make sure it is the right lock for your entrance, properly installed, and supported afterwards.

Protection Throughout the Buying Journey

Different risks appear at different stages. The Interlock Assurance is designed around all three.

Before Installation

We check the fit first.

We assess your door, gate and installation conditions before recommending suitable models whenever possible.

During Installation

We take responsibility for our work.

Your installation is handled by Interlock's installation team, with workmanship coverage after the job is completed.

After Installation

You still know who to call.

If you need troubleshooting or support afterwards, our Singapore-based team remains available to assist.

Assurance 01

No-Fit, No-Fee

If we cannot properly install a suitable lock, you should not have to pay for a failed installation.

Digital locks are not universally compatible with every door or gate. Door thickness, existing lock position, frame design, gate clearance and other physical conditions can affect what can be installed.

That is why Interlock takes a compatibility-first approach. Before your appointment, we may request photos and measurements so we can recommend suitable models and prepare alternatives where necessary.

Our No-Fit, No-Fee promise If the planned digital lock cannot be properly installed when our installer assesses the entrance onsite, and we are unable to provide a suitable compatible alternative, you will not be charged for the unsuccessful installation.

Where another suitable model can be installed, our team will explain the available option before proceeding.

Assurance 02

30-Day Installation Workmanship Guarantee

If an issue is caused by our installation workmanship, we will make it right.

Even a good digital lock depends on correct installation. Alignment, positioning, fitting and the interaction between the lock, door and frame all matter.

Interlock provides a 30-day workmanship guarantee on our installation.

If the problem is caused by our workmanship Contact us within 30 days of installation. Once confirmed as an installation workmanship issue, we will arrange to rectify it without an additional workmanship charge.

This workmanship guarantee is separate from the digital lock's product warranty and does not cover unrelated door, gate, frame or building-condition issues.

Separate Protection

Product Warranty

The Interlock Assurance protects you against compatibility and installation workmanship risks. The digital lock itself is separately protected by its applicable product or manufacturer warranty.

For example, Interlock Mercury digital locks include a 1-year product warranty. Warranty periods for other brands or products may differ, so please refer to the relevant product page or ask our team before purchasing.

Why We Check Compatibility Before Recommending a Lock

A digital lock can be an excellent product and still be the wrong choice for a particular entrance.

Door thickness
Existing lock and mortise position
Door and frame construction
Gate-to-door clearance
Handle and lock clearance
Existing holes and cut-outs

This is why we may ask for photos or measurements before confirming a recommendation.

What the Workmanship Guarantee Covers

The workmanship guarantee applies to installation-related issues caused by work performed by Interlock during the installation.

It does not replace maintenance or product warranty coverage.

Issues outside installation workmanship may include:

  • Door, gate or frame movement and alignment issues that develop independently of the lock installation
  • Damage caused by misuse, impact, accidents or unauthorised modification
  • Work performed by another contractor after our installation
  • Digital lock hardware, electronic or component faults covered under the applicable product warranty
  • Conditions unrelated to the digital lock or Interlock's installation workmanship

If the cause is unclear, our team can help determine whether the issue relates to the lock, installation, door or surrounding structure before recommending the appropriate next step.

Interlock Assurance FAQs

Does No-Fit, No-Fee mean every digital lock will fit my door?

No. Different locks have different physical requirements. The purpose of our compatibility process is to identify suitable models before installation. If the planned model cannot be properly installed onsite and no suitable alternative is available, our No-Fit, No-Fee assurance applies.

Why do you need photos before recommending a digital lock?

Photos help us assess factors such as your existing lock, door construction, strike area, gate design and available clearance. This allows us to recommend more accurately before the installer arrives.

What happens if the installer finds that my chosen lock cannot fit?

We will first determine whether a suitable alternative can be installed. If there is no suitable compatible option, the unsuccessful installation is covered by our No-Fit, No-Fee assurance.

What does the 30-day workmanship guarantee cover?

It covers installation-related problems that are confirmed to have been caused by Interlock's workmanship. If confirmed, we will rectify the workmanship issue without an additional workmanship charge.

Is the workmanship guarantee the same as the product warranty?

No. Workmanship coverage relates to the installation itself. Product warranty relates to faults with the lock or its covered components. The applicable product warranty varies by product and brand.

What if I am not sure whether my problem is the lock, installation or door?

Contact our support team and describe the issue. Where necessary, we can help troubleshoot and determine the likely cause before advising the appropriate next step.
