At CD Locksmith, we help protect your home, property, and peace of mind. Our expert team offers key safe installation and wireless alarm system setup for individuals, families, landlords, and those looking after vulnerable people. Whether it’s to support independent living, provide secure access for carers, or protect a second home, we provide reliable solutions that put safety first.
Security today means more than locking your door. It’s about making sure the right people can get in when needed — and knowing someone is alerted if something goes wrong.
A combination key safe stores spare keys outside your property. Only those with the correct code can open it. A wireless alarm system, meanwhile, alerts family, carers, or emergency responders to danger — whether that’s a fall, a fire, or a break-in. Together, these systems work to protect people and property in a smarter, more accessible way.
Our professional installation service ensures both systems are fitted properly, securely, and in line with police and insurance requirements.
We install some of the most trusted key safes on the market, including the Supra C500 Pro. This model is police approved, meaning it meets strict guidelines set out in the Secured by Design initiative. It’s also certified under LPS1175 Issue 8, one of the highest security ratings for domestic access devices.
With a toughened metal body and reinforced design, the Supra C500 Pro resists tampering and forced entry. It supports over 4,000 code combinations and features a discreet weather-resistant cover for external wall mounting.
We only install on solid surfaces like brick or concrete — ensuring long-term stability and security. Every installation includes a demonstration of how to set and change your access code, as well as advice on location and best practice.
Wireless alarms offer instant protection, without the need for cables or landlines. These systems work across a wide range of properties and are especially suited to:
Systems can include personal alarms, fall detection, motion sensors, and remote access via mobile apps. Most are connected to family or monitoring services, offering real-time alerts if something happens.
Unlike older analogue systems, our alarms work with digital landlines or SIM-based devices, giving you dependable coverage whether you’re at home or not.
We help you choose a setup that matches your needs — and install it without disruption.
Key safes and wireless alarms are ideal for:
A properly fitted system gives trusted people access when needed, and alerts you — or a monitoring service — the moment something goes wrong.
If emergency services are called, we can pass on the access code securely so responders can get inside without delay.
We believe in doing things properly. That means:
Our engineers are qualified, insured, and DBS-checked. We aim to book all installations within a working day window of 5–10 days after ordering, and most installations are completed within an hour.
Do I need a police-approved key safe?
If you want to meet insurer or care provider requirements, we strongly recommend one. Models like the Supra C500 Pro are rated to LPS1175 Issue 8 and recognised by police under the Secured by Design scheme.
Where should I put my key safe?
We’ll help you choose a safe location — ideally not right by the door. The key is to balance accessibility with discretion.
What happens if I forget the code?
We’ll show you how to reset your code combination securely. If you forget it entirely, we can help reset or replace the unit.
Can you fit the key safe and alarm on the same day?
In most cases, yes. This ensures both systems are correctly positioned and working together to support your home security.
Are these alarms suitable for someone with dementia or Alzheimer’s?
Yes. Many personal alarms are designed with simplicity in mind — with large buttons, fall sensors, and easy access for carers.
Will this affect my insurance?
Using a certified key safe and properly installed alarm may actually support your cover. But it’s always best to check with your insurer, especially if you’re storing vehicle keys or managing holiday lets.
Whether you’re looking after someone vulnerable, managing a property, or protecting your own peace of mind, CD Locksmith is here to help. Our combined key safe installation and wireless alarm system service is designed for real-life situations — giving you reliable access and real-time protection.
