Where LifeSafer actually reaches

These figures come from our own index of 10,531 installation points, not from the brand’s marketing. A network is only useful if it reaches the town where you have to drive every 30 to 60 days for a calibration.

LifeSafer appears at 2,230 of the 10,531 points we have on file — 21% of the market as we measure it — spread over 49 states and 1,741 towns and cities. 40% of those addresses also install a competitor’s device. That is worth knowing: the shop is not tied to one brand, so switching provider often does not mean switching garage.

In 450 of those towns it is the only installer on file. If you live in one of them, the price you are quoted is the price there is.

Not found in Hawaii, South Dakota — if you are there, one of the other providers is your route.

What LifeSafer costs

LifeSafer does not publish a single national price, and quotes vary by state and by the center doing the install. We are collecting confirmed quotes and will publish them here with the date each one was checked — not before.

Getting hold of them

LifeSafer customer service and phone numbers

We are not LifeSafer’s support desk and cannot see your account. These are the company’s own published lines, listed because they are unreasonably hard to find when a device has just locked you out.

customers and new enquiries

Only LifeSafer can do these

  • Billing disputes and the balance on your account
  • A lockout code when the device will not let you start
  • Booking or moving a calibration appointment
  • The removal paperwork your state agency needs
  • Anything the monitoring authority has already been told about your device

These we can help with

  • Finding a certified center closer to you than the one you were assigned
  • Checking what your state caps or requires, so you know what is negotiable
  • Comparing what another approved provider charges before you commit

Verified with the state

Where LifeSafer is approved, and under which device

States publish their own lists of vendors allowed to fit an interlock, and the model name on that list is what your paperwork has to match. This is the one claim about a provider that does not come from the provider.

StateDevice on the state listWho publishes it
TexasFC100 and L250Texas Department of Public Safety, approved devices list · checked 2026-08-30
FloridaL250Florida Department of Highway Safety and Motor Vehicles · checked 2026-08-30

Approval in one state says nothing about the next one: each program keeps its own list, and a device accepted in Texas may not be accepted where you live. If you move mid-term, this is the first thing to check — before the provider tells you it is fine.

Compare before you commit

Providers rarely differ enough on the device to matter. The difference you feel is the monthly fee, the lockout policy, and how far you drive every 30 to 60 days for a calibration.
