Frequently Asked Questions (Mailbox Locks)
- What should I do if I lost my HDB letterbox key?
- If you've lost your HDB letterbox key, don't worry. Contact our 24/7 emergency service. We can either unlock your existing letterbox for a SGD 25 fee, or we can replace the entire lock with a new digital one, which includes the unlocking service. This is often the best time to upgrade to a keyless solution.
- How much does it cost to change a mailbox lock in Singapore?
- Our prices for changing a mailbox lock start from just SGD 50. This price includes the new lock and the full installation service. If your current lock is locked and you've lost the key, an additional SGD 25 unlocking fee applies.
- What warranty do you provide?
- All our digital and mechanical mailbox locks include a **1-Year Seller Warranty with on-call support** – **Singapore's Only One!**, giving you complete peace of mind.
- How long does the installation take?
- Installation is very fast, typically taking only 15–30 minutes. We provide on-call service, and our standard lead time is just 1–2 business days after you confirm your order.
- Will you damage my letterbox?
- No. Our technicians are professional locksmiths who use specialized tools to ensure a clean installation or replacement with no damage to your letterbox door.
- Do your digital mailbox locks require batteries?
- Our most popular password and key models (Product 1, 2, 3, 6, 7) are fully mechanical and do not require batteries. Only the "Smart Battery-Powered" locks (Product 4, 8) use CR2032 batteries, which last over 12 months.
- What is "Retrieve Password" on some locks?
- Our models like Product 2, 3, 6, and 7 have a password retrieval mechanism. This means if you forget your code, you don't need to break the lock. We can use a master key or tool to find your password for you. Crucially, this key cannot open the lock directly.
- Can I replace my old mechanical lock with a digital one?
- Yes, absolutely! Our service is primarily focused on replacing old, faulty, or key-based locks with modern digital and smart options. Our team ensures a perfect fit for nearly all HDB and condominium letterbox models.
- Do you sell Traditional Key Locks?
- Yes, we do! If you prefer a simple solution, our PRODUCT 5: Traditional Key Mailbox Lock is available for SGD 50, which includes installation and two new keys.
- How secure are mechanical digital letterbox locks?
- Mechanical digital locks are highly secure. Especially our Product 6 (4-Digit Lock), which offers thousands more combinations than standard 3-digit locks, making it extremely secure against guessing.
- Do you provide emergency service outside of regular business hours?
- Yes, we offer 24/7 on-call support for emergency services, especially for mailbox unlocking (SGD 25 fee applies). We understand that urgent issues like lost keys can happen anytime.
