Keyless entry installation typically costs $150-$600 for an aftermarket car system or $120-$500 for a keypad or smart lock installed on a home door. The price depends on whether the job involves vehicle wiring and fob programming or a door lock replacement, plus the system type, vehicle compatibility, labor, and local rates.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Aftermarket car keyless entry | $150 | $350 | $600 | System and installation; basic remote access |
| Car remote-start and keyless bundle | $300 | $650 | $1,200 | Higher for newer vehicles or complex integration |
| Residential keypad deadbolt | $120 | $250 | $400 | Installed on a compatible existing door |
| Residential smart lock | $200 | $350 | $500 | Wi-Fi or hub features may raise the price |
| Replacement or programmed car fob | $50 | $150 | $350 | Price depends on fob type and vehicle |
What car and home keyless entry installation usually costs
For a car, a basic aftermarket keyless-entry system with remote lock and unlock commonly totals $150-$600, including parts and installation. A straightforward older vehicle is often near the low end; a newer model with factory security integration or complex wiring can approach or exceed the high end. The typical installed price is about $350.
For a home, a keypad deadbolt installation is often $120-$400, while a connected smart lock is commonly $200-$500 installed. Those estimates generally assume one standard exterior door, a compatible bore and backset, and no major carpentry. A lock alone can cost less if the homeowner installs it.
First identify whether the quote is for a vehicle system or a door lock; the labor and equipment are not interchangeable. A car quote should specify the control module, remotes, wiring, and programming. A residential quote should identify the lock model, any hub or bridge, installation, and whether the existing hardware is removed.
Assumptions: Typical U.S. prices, standard products, one vehicle or one door, and normal access; regional labor and compatibility can change the total.
How car wiring and door hardware shape the installed quote
Installation estimates divide differently by job type. Car systems require compatible electronics and careful wiring; home locks require hardware that fits the door and, for connected models, setup of the app or network. The table gives common ranges for each work group, not a mandatory bill format.
| Cost component | Aftermarket car system | Residential lock | What can change the charge |
|---|---|---|---|
| Materials | $50-$250 | $60-$300 | Remote count, lock grade, smart features |
| Labor | $75-$250 | $50-$150 | Access, wiring, door fit, setup time |
| Equipment or accessories | $0-$150 | $0-$150 | Bypass modules, hubs, bridges, extra remotes |
| Programming and testing | $25-$150 | $0-$75 | Vehicle pairing or network configuration |
| Removal or door adjustment | $0-$100 | $0-$200 | Old alarm removal, drilling, latch or strike work |
Car labor is commonly billed as a package, but an independent installer may quote $75-$125 per hour. A residential locksmith may charge $50-$125 per hour, sometimes with a service-call minimum.
Ask for parts, installation, programming, and any service-call fee as separate quote lines. This makes it easier to see whether a low advertised price excludes a required interface module, extra fob, door modification, or final test.
Which vehicle wiring and door measurements change the price?
Vehicle compatibility is a major price variable. A basic system that only operates power locks may need less integration than a setup tied into an alarm, factory immobilizer, trunk release, or remote start. Some vehicles require a data-interface or bypass module costing roughly $40-$150, and additional programming can add $50-$200.
Door dimensions also matter. A standard door with a typical 2-1/8-inch lock bore and compatible backset usually needs little or no modification. If the door has an unusual bore, misaligned strike, thick slab, or multipoint lock, extra labor or specialty hardware can add $50-$200 or more. A smart lock may also require a reliable connection within roughly 30-50 feet of its hub, depending on walls and the product.
Features push prices upward in both categories. Adding remote start to a car keyless-entry package can bring installed totals to $300-$1,200; adding two-way confirmation or extra remotes also increases parts cost. For home locks, Wi-Fi, fingerprint readers, multiple user codes, and built-in alarm features can add $50-$200 over a basic keypad model.
Compatibility checks before purchase can prevent paying twice for parts or labor. Give an installer the vehicle year, make, and model, or provide the door thickness, lock measurements, and existing hardware details before accepting a quote.
How installation time and service calls affect the labor bill
A straightforward home lock swap often takes 30-90 minutes. Drilling, repairing a loose door, adjusting a latch, or configuring a hub may extend the visit to two or three hours. Some locksmiths add a $50-$100 trip or minimum charge, especially for a single lock or an appointment outside normal hours.
Automotive installation commonly takes two to four hours for an aftermarket keyless-entry system. Integration with an alarm or remote start can take three to six hours, particularly when trim must be removed or wiring access is limited. A specialist may charge a diagnostic or programming fee of $50-$150 if the vehicle’s wiring or existing system needs troubleshooting.
Labor is largely determined by access and integration, not just the advertised install time. A quote should state whether testing is included and whether the installer will correct a failed pairing or wiring issue during the same visit.
Three realistic quotes for common keyless entry jobs
The examples below show how similar-looking projects can produce different totals. They assume normal access and standard daytime scheduling; taxes and unusually high local rates are excluded.
| Job and specifications | Parts | Labor and setup | Estimated total |
|---|---|---|---|
| Older sedan, basic remote lock/unlock, two remotes | $90-$180 | 2-3 hours, $100-$225 | $190-$405 |
| Newer SUV, integrated remote start and keyless entry | $300-$650 | 3-5 hours, $200-$450 | $500-$1,100 |
| Home entry door, keypad deadbolt replacing compatible deadbolt | $80-$200 | 1-1.5 hours, $75-$150 | $155-$350 |
In the first example, a required vehicle interface module or extra fob could add $50-$150. In the second, the vehicle’s electronics and security requirements account for much of the spread. In the home example, replacing a mismatched latch or repairing a damaged door can add $50-$200.
Compare estimates only after confirming that each quote covers the same equipment and tasks. One installer may include two remotes and programming while another prices a system with one remote and bills programming separately.
Regional labor rates for vehicle installers and locksmiths
Installed prices often run 10%-25% higher in major coastal cities and high-cost metro areas than in smaller Midwestern or Southern markets. Dense urban locations may also have parking or access fees. Rural customers may face a larger travel charge even when hourly labor is lower, particularly for a specialized automotive installer.
For example, a $350 basic car installation in a moderate-cost market might quote at $385-$440 in a high-cost metro before optional upgrades. A $250 home keypad installation could rise to about $275-$315 under similar labor differences. These are comparison estimates, not fixed regional price lists.
Local availability affects the final quote. A general locksmith may install a standard keypad lock, while an automotive electronics specialist is more likely to handle factory-security integration. If few qualified installers serve an area, travel time and scheduling can outweigh the lower local hourly rate.
Use regional ranges to screen quotes, then compare scope and credentials within the same market. A price difference is not evidence of overcharging unless the products, warranty, programming, and service included are also comparable.
When a replacement fob or keypad costs less than a full system
If a car already has factory keyless entry, replacing or programming a fob is usually cheaper than adding an aftermarket system. A basic replacement fob may cost $50-$150, while a smart key or proximity fob can run $150-$350 or more, including cutting and programming. Dealer pricing can be higher; independent automotive locksmiths may offer compatible options.
For a home, a standalone keypad deadbolt can cost $60-$180 for the product, compared with about $100-$300 for many connected smart locks. The less expensive option still provides code access but may lack remote app control, activity alerts, or integration with home automation. If the existing deadbolt works, replacing only the interior or exterior component may not be possible for every lock model.
Repair can also make sense. A car’s failed remote may need a battery, resynchronization, or a button repair rather than a new control module. A sticky door latch may need adjustment rather than a more expensive lock. A diagnostic visit commonly costs $50-$150, which can be worthwhile if it confirms the fault before a full replacement.
Pay for a full installation only when the existing system cannot provide the required access reliably. Confirm the cause of failure and ask whether a compatible replacement part can retain the factory system.
How to lower the quote without sacrificing reliable access
Keep the scope limited to the functions actually needed. For a car, remote lock and unlock alone costs less than adding remote start, trunk release, alarm integration, or upgraded two-way remotes. For a home, a keypad lock may meet the need without a Wi-Fi bridge, fingerprint reader, or subscription-connected service.
Use standard, compatible equipment and verify measurements before ordering. A door that accepts a common deadbolt can avoid drilling and specialty hardware charges. For a vehicle, confirming the exact year, trim, and factory options helps the installer choose the right interface and avoid return visits.
Compare at least two itemized quotes and ask about warranty coverage, programming, number of remotes or codes, and service-call fees. Bundling several locks on one visit may reduce the per-lock labor charge, while scheduling during normal business hours can avoid emergency or after-hours fees. Prepare the door area or vehicle access point, but do not remove trim or alter wiring unless the installer requests it.
The biggest savings usually come from avoiding unnecessary features and repeat labor, not choosing the lowest-priced hardware alone. A low quote that omits compatible modules, setup, or testing may cost more after required add-ons are included.
