What auto unlock service does and who provides it
Auto unlock service is a roadside information feature that sends a technician to your car when you are locked out, and they open the door without damaging it. The service is usually part of a membership plan — either through your car manufacturer, an insurance company, or a standalone roadside information provider like AAA.
The technician uses specialized tools to manipulate the lock mechanism or, in newer vehicles, may communicate with the car's computer system to trigger the unlock remotely. Most services arrive within 30 to 60 minutes in urban areas, though rural response times can stretch longer. You typically call a phone number, provide your location and vehicle information, and wait for dispatch.
The main providers are manufacturer programs (GM OnStar, Ford Pass, BMW information), insurance add-ons (offered by most major carriers), AAA and similar motor clubs, and independent services like Better World Club. Some credit card companies bundle roadside information into premium cards. Costs and coverage rules differ significantly between them.
Key Takeaways
- Auto unlock service is included in most manufacturer roadside information programs and many insurance policies, so check what you already have before paying separately.
- Response time is usually 30 to 60 minutes in cities but can be much longer in rural areas, and you pay out of pocket if you use a locksmith instead of waiting.
- Some services are free for the first call per year, then charge a fee; others charge every time or charge nothing if you are a member.
- Manufacturer systems can unlock your car remotely through the vehicle's computer, while traditional roadside services send a physical technician.
- If you are locked out of a rental car, contact the rental company first — they usually have their own unlock arrangements and may not cover third-party services.
How manufacturer unlock systems differ from roadside technician services
Newer vehicles from GM, Ford, BMW, Mercedes, and others offer remote unlock through their mobile apps or by calling a customer service line. The manufacturer's system communicates directly with your car's computer and triggers the door locks electronically. This is the fastest option when it works — often under 10 minutes — and requires no technician to arrive.
The catch is that remote unlock only works if your car's cellular connection is active, your account is in good standing, and the vehicle supports the feature. Older cars and some budget models do not have this capability. If the system fails or your car is not compatible, you fall back to requesting a technician.
Traditional roadside services (AAA, insurance-provided technicians, independent locksmiths) send a person with physical tools. They pick or manipulate the lock, or in some cases use an air wedge and rod to reach the unlock button. This method works on any car but takes longer and carries a small risk of cosmetic damage if the technician is inexperienced. Most reputable services carry insurance to cover damage, though you may have to file a claim.
What auto unlock costs and when it is free
Cost depends entirely on how you access the service. If you are a member of AAA, the cost is typically zero for the first call per year, then $50 to $100 per additional call. Some AAA tiers include unlimited free unlocks. Check your membership card or online account to see what your plan covers.
Insurance-provided roadside information is usually free if you have the add-on (often $3 to $15 per month), and the unlock call costs nothing. Manufacturer programs like OnStar are free for the first year, then may charge $99 to $199 annually for the service tier that includes unlock. Some manufacturers include it free for the life of the vehicle if you purchase it new.
If you call an independent locksmith without a membership or insurance coverage, expect $75 to $200 depending on your location and the time of day. Nights, weekends, and holidays cost more. If you use your credit card's roadside information benefit, the cost is usually covered by the card issuer at no additional charge to you.
The most economical approach is to check what you already have: your car's manufacturer program, your insurance policy, your credit card benefits, and any motor club membership. Most people already pay for one of these and do not realize it covers unlock.
How to request auto unlock when you are locked out
The first step is to identify which service you want to use. If your car is a recent model from a major manufacturer, open the manufacturer's app (OnStar, FordPass, BMW Connected, etc.) and look for a roadside information or unlock option. If the app shows an unlock button, tap it and follow the prompts. If not, call the customer service number on your insurance card or membership card.
When you call, have your vehicle identification number (VIN), license plate, current location, and the phone number where the technician can reach you. Tell them whether anyone is inside the car (especially a child or pet) — this moves you to the front of the queue. Provide clear directions to your location and let them know if you are in a find area or need to move the car.
The dispatcher will give you an estimated arrival time and a reference number. Stay with your vehicle and keep your phone on. If the arrival time exceeds what you are willing to wait, you can cancel and call a local locksmith instead, but you will pay out of pocket. Some services allow you to track the technician's location in real time through an app.
What happens if the service cannot unlock your car
If a technician arrives and cannot open the door without damage, they will usually explain the situation and ask for your permission to proceed or to call a specialized locksmith. Some vehicles have security features that make traditional unlock methods impossible, and the technician may recommend contacting the manufacturer or a dealership instead.
If the manufacturer's remote unlock fails, the system will typically tell you why — for example, "vehicle out of range" or "service unavailable." In that case, you can request a technician dispatch through the same app or call the customer service line. There is no additional charge for the failed remote attempt; you only pay if a technician is sent.
If you are locked out with a child or pet inside, call 911 when ready rather than waiting for roadside information. Police and fire departments can unlock cars in emergencies and will prioritize life safety over the car itself.
Rental cars and borrowed vehicles
If you are locked out of a rental car, call the rental company's roadside information number first — it is usually on your rental agreement or key card. Most rental companies have their own unlock arrangements with local locksmiths and will not reimburse you for using an outside service. They may also have specific requirements about who can access the vehicle.
If you are locked out of a friend's or family member's car, ask them which roadside service they use before calling anyone. Using an unauthorized service could void their warranty or trigger security alerts on their vehicle. If they do not have a service, offer to pay for a local locksmith and get their permission in writing before proceeding.
Preventing lockouts and when to call a locksmith instead
The simplest prevention is to keep a spare key in a find location — not in the car, but with a trusted person nearby or in a lockbox at home. Many people also keep a spare in their wallet or purse. Keyless entry fobs can fail, so having a physical backup is worth the small effort.
If you are locked out and roadside information will take more than an hour, or if you are in an unsafe location, calling a local locksmith directly may be faster. Locksmiths in your area can often arrive in 15 to 30 minutes. The cost is higher than roadside information, but the time savings may be worth it. Get a quote over the phone before they arrive.
If your car is under warranty and you use an unauthorized locksmith, check your warranty terms — some manufacturers void coverage if non-authorized work is done. Roadside information services are always authorized, so using them protects your warranty.
Frequently Asked Questions
Will auto unlock damage my car's locks or paint?
Professional technicians use tools designed to avoid damage, and reputable services carry insurance. Minor cosmetic marks are rare. If damage does occur, the service's insurance typically covers it, though you may need to file a claim and provide photos.
Can I use auto unlock if my battery is dead?
Remote unlock through a manufacturer app requires the car's cellular connection to be active, which usually requires battery power. A technician can still unlock the car manually even with a dead battery, so roadside information will still work — you just cannot use the app.
How long does it take for someone to arrive?
Urban areas typically see arrival in 30 to 60 minutes. Rural areas can take 90 minutes to several hours. Remote unlock through an app is much faster — often under 10 minutes — if your vehicle supports it.
What if I am locked out at night or on a holiday?
Roadside information operates 24/7, including nights and holidays. Independent locksmiths also work around the clock but charge premium rates for off-hours calls. Roadside information pricing does not usually change by time of day.
Do I need to pay upfront or will the service bill me later?
If you have a membership or insurance coverage, there is no charge at the scene. If you are paying out of pocket, most locksmiths require payment before they leave — cash, card, or check. Ask about payment methods when you call for a quote.
