Don't Buy a Smart Lock in Singapore Before Checking These 5 Things — Common Mistakes Homeowners Regret

With so many smart locks available in Singapore, it's easy to focus on flashy features, promotional prices, and spec sheets while overlooking what actually matters after installation.  

Before you press "Buy Now", run through this checklist. These are the five things every Singapore homeowner should check before committing to a smart lock.

Mistake 1: Neglecting Door & Gate Compatibility 

Check that the lock you choose is compatible with your specific door and gate. A lock that's not suited to your gate will not install properly or operate smoothly over time. 

PRISM+ solves this by also selling doors and gates custom-built to fit your needs, reducing the guesswork on your end.

Mistake 2: Emergency Backup Options 

Most smart locks will provide multiple low-battery warnings well before the batteries need replacing. But life gets busy. If the batteries eventually run flat, what happens next? 

This is why it's important to choose a smart lock that offers emergency access methods. Features such as a physical key override and emergency Type-C power input provide a safety net when battery replacement is delayed. 

For example, the PRISM+ Spectre and Sentry Ultra Smart Locks support both physical key access and Type-C emergency jumpstart functionality.

Mistake 3: Not checking the lock’s durability

A common mistake is focusing only on features while overlooking compliance and durability. Before buying, check whether your home has a fire-rated main door. If it does, the digital lock installed must also be certified for use on fire-rated doors to ensure compliance and maintain the door's fire-resistance performance.

Next, consider durability. Singapore's heat and humidity can accelerate corrosion and wear over time, so look for locks built with quality materials and tested for long-term reliability.

PRISM+ smart locks are fire-rated for use on fire-rated door installations, built with aerospace-grade aluminium, and subjected to rigorous military-grade reliability testing, providing homeowners with both compliance and durability for everyday use.

Mistake 4: Underestimating the importance of after-sales support

Smart locks have firmware updates, components experience wear and tear, and issues that require assistance. Buying from a brand with limited local presence means that if something goes wrong, you’re on your own.

Before buying, check:

• Does the brand have a Singapore warranty?

• Is there a local service centre or authorised installer network?

• How long is the warranty? 3 years is the benchmark for a product that serves as your home’s primary access point and is used multiple times every day. 

Homeowners should have confidence that issues will be taken seriously and resolved promptly.

PRISM+ smart locks come with a 3-year warranty structure, with one year of comprehensive coverage for both parts and labour, and the following two years cover replacement parts. Additionally, homeowners can also opt for comprehensive 3-year or 5-year extended warranty plans, at an added fee. PRISM+ local customer support teams are committed to handling every case with urgency and care, ensuring homeowners receive timely assistance.

Mistake 5: Buying on price alone

Many homeowners focus on finding the cheapest smart lock available, but this lower price often comes with trade-offs. These can include less durable mechanisms, poorly maintained apps, inconsistent connectivity, or materials that may wear out faster in Singapore's hot and humid climate.

While a budget lock may save you money initially, the cost of replacing a faulty lock can quickly outweigh those savings. Instead of comparing prices alone, consider factors such as reliability, build quality, warranty coverage, and after-sales support.

To save costs, bundle promotions selling door and gate locks often gives more cost savings than buying each individually.

For example, the PRISM+ Spectre Bundle combines both locks at a lower total cost.

The pre-purchase checklist

• Gate and door: Are the locks compatible with your door and gate?

• Backup Access: Does this model offer emergency access methods?

• Durability: Is it SS 332 certified? Can the lock withstand Singapore’s humidity? 

• Support: Is there a Singapore warranty of at least 3 years and local service presence?

• Price: What’s the best balance between price and quality of the product, app and after-sales support? Are there additional bundles or promotions you can take advantage of?

Taking a few extra minutes to evaluate the points can help you avoid costly mistakes. The right lock should not only secure your home today, but continue to provide convenience and peace of mind for years to come.
