After buying a house, take control of keys, garage access, alarm codes, and security accounts first. Then review inherited equipment, check entry points and coverage gaps, and verify detection, camera recording, notifications, and any monitoring service before relying on the system. This home security checklist for new homeowners puts those steps in order.
What Security Should You Check First After Buying a House?
Organize the handover around three stages:
Take Control of Existing Access
Arrange for a qualified locksmith to rekey or replace exterior locks as appropriate. Account for side doors, patio doors, the garage-to-house door, and detached buildings. Review garage remotes and wireless keypad access using the opener manufacturer's procedure.
Electronic access needs its own handover:
- Establish your own security account and confirm appropriate administrator rights.
- Review alarm users, personal and shared codes, key fobs, and access credentials.
- Review camera viewers, recorder accounts, and any separate video service accounts.
- Identify installer and security-company access, retaining only the providers you authorize.
- Remove previous occupants and obsolete permissions through the supported process.
Do not make the seller's shared login your permanent account. Verify your own access before the handover ends, and keep recovery details under your control.
For Ajax, user roles and permissions determine what each person can manage. Being able to arm the alarm does not necessarily mean you can remove other users or change all settings.
Before factory-resetting an inherited alarm, identify the system and confirm the manufacturer's or provider's supported ownership-transfer procedure. Resetting equipment, transferring account ownership, and removing previous users are separate actions; follow the supported process for each.
Find Out What Security Equipment Came With the House
Build a room-by-room inventory. Record model names, locations, service contacts, and any available installation documents. Include:
- The alarm panel or hub, keypads, sirens, and backup power equipment.
- Door and window contacts, motion detectors, and glass-break detectors.
- Cameras, doorbells, recorders, and configured recording storage.
- Installed smoke, carbon monoxide, heat, and water-leak devices.
- Network connections and any cellular communicator or service associated with the alarm.
Check the purchase documents and record equipment ownership and provider contacts. Keep current service status and any confirmed activation dates alongside the inventory.
For smoke and CO devices, identify manufacturer testing and replacement instructions. Confirm separately whether they operate locally or also report through a connected service.
Decide What Can Stay and What Needs Review
Flag questionable equipment in your inventory. Document its model, visible condition, ownership, support status, and obvious faults. ASPEX Secure can assess whether equipment should be retained, upgraded, integrated, or replaced as part of a property-specific review.
Check Doors, Windows, Glass, and Interior Routes
Compare the inherited layout with how your household will use the home. Check the garage-to-house door, patio access, accessible windows, and any detached space you intend to use.
Ask the installer to show which openings and interior routes are protected, explain disabled or bypassed zones, and demonstrate the intended nighttime mode. Opening, glass-break, and motion detection serve different purposes; record any gaps for review.
Point out changes from the previous household: pets, a converted room, a different daily entrance, or furniture that blocks a detector. Recheck affected areas after unpacking or renovations.
Check Camera Access and Recording
From your own account, open each camera and play back a newly recorded event. Confirm where recordings are stored, whether you can retrieve them, and whether a recording subscription must be activated in your name.
Check whether inherited views show the entrances, package area, or garage activity you need to review, including after dark. If a view needs changing, use our guide to where to place security cameras around a Houston home.
Review Monitoring and Communication
Ask the provider to confirm the activation date, property address, authorized contacts, verification details, and included event types for your monitoring account. Replace the previous owner's response contacts and understand the agreed alarm-handling procedure.
App access does not confirm active professional alarm monitoring. With a compatible, active service, operators review received events and follow account procedures; dispatch and response times are not guaranteed.
Tell the installer if you are replacing the router, changing internet providers, or canceling a service associated with the alarm. Confirm who maintains any cellular subscription. Have the resulting communication paths and backup-power arrangements checked after those changes.
Test the System Before You Depend on It
Coordinate testing with the responsible security provider and monitoring service first. Follow the procedure for the exact equipment, including any required monitoring test period. Do not assume an in-app device test suspends all alarm handling.
Verify three separate outcomes where applicable:
- Detection: The intended device responds at its installed location and identifies the correct opening or area.
- User notification: The required alert reaches the intended authorized recipient with useful event information.
- Monitoring receipt: The monitoring service confirms receipt and correct identification of the agreed test signal.
Ajax recommends detection-area and signal-strength tests when checking detector operation after installation. Those checks do not, by themselves, demonstrate the complete monitoring workflow.
Keep the test results and follow-up list. Confirm that testing has ended and normal protection is restored. Before handover, household members should practice arming and disarming and know how to recognize faults and contact support.
New Homeowner Security Checklist
Use this final handover check. Record a next step for anything unresolved.
- Exterior keys and garage access have been reviewed and updated.
- My own security account has the permissions I need.
- Previous users, obsolete codes, and camera-sharing permissions have been addressed.
- Equipment, ownership, service providers, and subscriptions are documented.
- Important entry points and coverage gaps have been reviewed.
- Smoke, CO, and other safety devices have a documented review or service plan.
- Camera views and newly recorded footage have been checked.
- Monitoring status, address, authorized contacts, and event scope are confirmed.
- Communication and backup arrangements have been reviewed and tested as appropriate.
- Detection, required app alerts, and monitoring receipt have been checked separately.
- Normal operation has been restored, and household members know the basic controls.
