At Dumo Seguridad, we offer keyholding and alarm response services in Barcelona with security guards certified by the General Directorate of Police and direct connection to our Alarm Receiving Centre.
We keep your keys in a secure armored safe, and when the alarm is triggered, a security guard is dispatched immediately to verify the incident, so you don’t have to respond personally in the middle of the night.
Our alarm response service with private security complies with Law 5/2014 on Private Security and operates with geolocated patrols throughout Barcelona to ensure minimal response times.
Barcelona presents unique security and mobility challenges that make it essential to have a professional and reliable keyholding and alarm response service. The urban density of the Eixample, the narrow streets of the Gothic Quarter, and the nighttime traffic on the Rondas complicate rapid emergency response.
When your alarm goes off at three in the morning, you would have to get up, travel across Barcelona to your property, and handle the situation personally. During that 30–40 minute journey, if a real intrusion is occurring, the intruders have enough time to act.
With a professional private security keyholding service like ours, you delegate this risk entirely. Our licensed security guards are dispatched immediately to verify the situation, and you receive a complete report of what happened without leaving your home.

Residential communities and parking facilities face particular challenges due to high urban density and the complexity of night-time access. When the alarm goes off at four in the morning, the president or administrator must find someone available to respond and handle the situation.
With our keyholding and alarm response service, the keys are deposited under a signed record in an approved safe with a unique security code. When the Alarm Receiving Centre detects a triggered alarm, a security guard licensed by the General Directorate of Police is dispatched immediately. The guard performs a full perimeter check, enters if necessary, and remains on-site until everything is secured. Residents receive a detailed report without anyone having to travel to the property.
Our alarm response service, staffed with security guards authorized by the Ministry of the Interior, provides immediate professional response. The protocol includes full perimeter verification, controlled access using the held keys, visual inspection of technological installations, and professional accompaniment for technicians or the Mossos d’Esquadra if required.This service is especially valuable for companies with executive teams in other cities, who can remotely supervise the entire intervention through the digital report we generate.


Retail stores and shopping centers often require access outside regular business hours for cleaning, restocking, or maintenance. Handing over keys to cleaning companies or suppliers creates a risk of losing control over who actually has access to the premises.
With our keyholding service, the keys remain securely stored in an armored safe under our exclusive control. When a scheduled opening is required, a licensed security guard is dispatched at the agreed time, opens the premises, supervises the activity, and ensures everything is properly secured upon leaving.This private security keyholding service also covers night-time emergencies with immediate response.
Industrial warehouses and business parks are often located far from residential areas, with limited night-time security presence. Police response times can be significantly delayed when prior verification is required.
Our private security alarm response service for industrial warehouses operates with strategically distributed zone patrols. When the Alarm Reception Centre is triggered, our nearest guard is dispatched with the held keys to carry out the intervention. The security guard performs an initial perimeter check, controlled access if necessary, and secures the premises until the Mossos d’Esquadra arrive.


Our keyholding service involves the secure deposit of a key copy in an authorized safe, under the exclusive control of authorized personnel. Keys are recorded under a signed log and identified with an internal code without any visible reference to the property, ensuring maximum confidentiality and traceability.
This custody allows access to the property in case of an emergency, facilitates entry for authorized technicians such as plumbers or electricians, and prevents the owner or administrator from having to travel to the site for any incident.
The alarm response service is activated when the Alarm Receiving Centre detects a signal or incident. At that moment, a patrol is dispatched to carry out on-site intervention at the property.
The security guard performs an external perimeter check and, if authorized by protocol, an internal verification using the held keys. In case of confirmed intrusion or damage, the Mossos d’Esquadra or relevant emergency services are notified, and the guard remains on-site until the situation is fully secured.

Our keyholding and alarm response service combines professional key custody in an armored safe with the immediate dispatch of licensed security guards when your alarm is triggered. The protocol is designed to ensure full traceability and compliance with Law 5/2014 on Private Security, from the moment we receive your keys until we intervene in any emergency.
Keys are received under a signed record and identified with a unique security code, with no label revealing the property address. They are stored in a fireproof, armored safe at an authorized central location, accessible only to authorized personnel. This keyholding service ensures that keys are fully protected and traceable at all times.
When the Alarm Receiving Centre detects a signal, the response protocol is activated automatically. We receive the incident immediately, including access details and type of signal, whether intrusion, fire, or panic. Our private security alarm response service acts as the first line of action, preventing the owner from having to manage the crisis personally.
The nearest intervention vehicle to the property in Barcelona is automatically dispatched via GPS. The goal is to arrive in record time to perform an initial exterior and perimeter check before any further action. Private security patrols in Barcelona are strategically positioned to minimize response times across all areas of the city.
Once on-site, the security guard uses the held keys to access the property and verify the interior if necessary. If an intrusion or incident is confirmed, the guard facilitates immediate access to the Mossos d’Esquadra or Barcelona Fire Department. The guard remains on the premises until everything is secure and rearmed properly, ensuring the property is not left vulnerable after the intervention.
After the intervention, we generate a technical report that is automatically sent to the client. It includes the exact arrival time, actions performed, condition of the installation after verification, and confirmation of secure closure of the property.
This document serves as proof for insurance purposes and ensures compliance with Private Security regulations of the Generalitat. Our private security response service provides full traceability of every action carried out.

Cameras and alarms detect and record incidents, but they do not act physically in an emergency. Our service provides immediate on-site verification by a licensed security guard who can access the property using the held keys. This drastically reduces vulnerability time, allows effective coordination with the Mossos d’Esquadra or Fire Department, and prevents you from having to travel personally in the middle of the night.
Intervention time depends on the property’s location, traffic conditions, and operational availability at the moment of the incident. Our service operates with strategically distributed, geolocated patrols to respond as quickly as possible in each area.
Unlike an owner, who may take 30 minutes or more to reach the site, our security guard acts as the first professional response link and coordinates with the Mossos d’Esquadra if necessary.
The security guard only accesses the property when expressly authorized by the personalized protocol. During protocol design, it is defined in which situations the guard can enter using the held keys and when they must wait for your telephone authorization. Every access is logged in the digital traceability system, and you receive a detailed report of all actions taken.
Our keyholding and alarm response service complements the police with immediate response without prior verification, the ability to access with held keys to assess real damages, and remain on-site until the premises are secured. The Mossos d’Esquadra may require prior verification before intervening. Our guard acts as the first on-site responder, verifies the situation, and facilitates immediate access for the police if an intrusion is confirmed.
The cost varies depending on property location, number of key sets to be held, estimated frequency of interventions, and additional services. During the personalized assessment, we provide a detailed quote tailored to your needs.
