Key Holding

At G3 Security Services, we understand that no property is safe without effective security measures and efficient team.

Our specialised key holding, alarm response and lock and unlock services are recognised as industry leading.

With our efficient service you can rest assured that our SIA licensed guards will provide a reliable solution, rapidly responding to any alarm call to ensure the absolute safety of your premises and immediately alerting the police if there are any signs of criminal activity.

Each security guard and officer are first aid trained and qualified in health and safety procedures, meaning that you’ll have extra protection in emergency situations.

Responsible and trusted key holding services

Our team will store a complete set of your keys in a secure, off-site premises. If you require immediate access to your property, our team will be able to grant entry whenever you need it – 24/7/365.

Instant and effective alarm response

When you leave your property at the end of the day, you’re leaving it vulnerable to crimes such as theft and vandalism. With G3 Security Services, a team of security professionals will be standing by to investigate alarm activations, no matter the time of day or night.

We pride ourselves on our average 30 minutes response time, so you have peace of mind that an SIA licensed security officer will arrive at the scene ASAP, ensuring any criminals or intruders are stopped in their tracks.

We will unlock and lock your premises for you.

Many businesses will allocate an internal key holder, responsible for locking and unlocking your business at the start and end of the day. Whilst this can work for some businesses, placing this responsibility on one employee can sometimes cause disruption to your business.

Be sure there’s always a trusted and reliable supervisor to open and close your business for you. With our highly trained officers on the case, you’ll also have peace of mind that your employees will never become a target for criminals looking to access your property.

Holding and Alarm Response is a simple and cost-effective security solution for companies wishing to secure their premises during out of office hours.

The benefit of the service is that it removes the need for any staff to respond to an intruder alert, fire, or security alarm activation during the night, giving you peace of mind that your site is in safe hands. You can also provide us access to your site through our key holding service to respond to any issues while you may be abroad or unable to access your site or property.

In the event of an intruder break-in or the activation of an alarm at your premises G3 will respond immediately, dispatching one of our local units who will possess the keys for your site and be able to enter it to respond to the alert. Our guards will then email a report to our control room which will allow us to formalise the procedure and email the report to the client.

This fully trained and vetted SIA licenced security officer will check the premises for signs of an intruder and in case of a false alarm will reset the security system. In the event of a break in, they will escalate the incident to Police and a nominated member of your staff. Our officer will remain on site until your premises are fully secured. Our guards will visit your site in our authorised vehicles and remain a visual deterrent until the issues is resolved.

G3 Security can also offer an out of hours service for your staff if you do not wish us to hold the keys to the premises. We will meet your member of staff at the location and check the premises with them, so they are not in any danger, remaining with them until the alarm is reset and the premises are secure or in event of a break in, waiting until the Police arrive.

Our 24-hour control room are available to respond to your site needs. We take all the relevant regulations and standards into consideration when storing your keys and ensure only authorised and licensed members of G3 Security can access them.

One dedicated staff member will arrange a time to meet with you to run through the procedures for setting and disabling alarms and locking and unlocking your premises and handover these requirements to our team.
