Own your security system: panels, installer codes and switching monitoring

Who owns the alarm panel, who holds the installer code, and what a dealer-locked panel means if you move or switch monitoring companies. With a checklist of questions to ask before you sign.

In short

A security system is only yours if you can keep using it after the contract ends, the company changes, or you move. That depends on three things: who owns the equipment, who holds the codes, and whether the system needs the company’s cloud service to work. Ask about all three before anything is installed.

Who owns the equipment

The codes, in plain words

We found no Washington law that makes an alarm company hand over the installer code. Get its answer in writing before you sign.

Dealer-locked and proprietary panels

A panel is effectively locked to one company when:

None of these is illegal, but each one makes switching harder. If portability matters to you, ask the company plainly: “Could another licensed company take over monitoring of this exact panel, and what would they need from you?”

Switching monitoring companies

  1. Read your contract. Find the term, the early termination charge and the renewal clause. As one example, ADT’s published residential terms (seen 2026-11-01) describe a 36-month monitoring contract where ADT may charge 75% of the monthly charges left in the initial term if you end it early. Terms differ by company, product and date, so read your own.
  2. Ask the old company to release the panel or give you the installer code, in writing.
  3. Have the new company confirm it supports your exact panel model and what it will replace.
  4. Check the new company’s licenses. Anyone paid to wire or service an alarm needs an L&I electrical contractor license covering alarm work (specialty 06, 02 or 01); check it on L&I Verify. Seattle requires alarm monitoring companies to be licensed with the city and publishes a list of licensed alarm companies. Tacoma requires an Alarm System Operator license for anyone monitoring alarms in the city.
  5. Tacoma’s device fee. Alarm companies pay Tacoma a $40 yearly fee per monitored system and may pass it on. Tacoma says the new company is not charged the fee again if the previous company already paid it that calendar year.

Watch for “takeover” pitches

In 2012, Washington’s Attorney General filed a consumer protection case against a door-to-door security company. The AG alleged its salespeople said they worked for the homeowner’s existing security company, or that they had “taken over” the existing service, and that customers wouldn’t face cancellation fees for switching. The company agreed to change its practices and pay restitution, and denied the allegations. The AG’s advice: call your existing company and ask about cancellation fees before agreeing to anything. See our guide to door-to-door alarm sales.

Questions to ask before you sign

Listings in our security systems directory show, where the company publishes one, its own statement about installer codes and local control (“The company says: …”, with a link). We don’t rate those statements. See how we list.

Common questions

What is the difference between a user code and an installer code?

A user code (sometimes called the master code) arms and disarms the system and adds other user codes. The installer code opens the panel's programming: sensors, zones, phone numbers and the monitoring account. With the installer code, a new company can usually take over the panel. Without it, it may not be able to.

Can my alarm company refuse to give me the installer code?

We found no Washington law that requires an alarm company to hand over the installer code. That is why the time to ask is before you sign: get the company's answer in the contract or in writing, and ask whether any programming lockout will be turned on.

How do I switch alarm monitoring companies in Washington?

Read your contract for the term, the early termination charge and the renewal clause. Ask the old company for the installer code or to release the panel. Then have the new company check that it can take over your exact panel model. In Seattle and Tacoma, check that the new company holds the city's alarm license.

Do I own the alarm equipment if it was free?

Not always. Equipment that comes free with a monitoring contract may be leased, financed or owned by the company. The contract says which. Ask who owns the panel, sensors and cameras, and what happens to them if you cancel or move.
