Subaru Ascent Key Replacement: Key Types by Model Year
The Ascent entered Subaru’s lineup for the 2019 model year. Ascent keys are electronic fobs, but the exact replacement depends on the vehicle’s year and trim, so share those details when you call.
2019–2022: Electronic key fob
These Ascent model years use an electronic fob for vehicle access and starting. The fob’s exact configuration can vary, so match the replacement to your specific Ascent rather than relying on appearance alone.
2023–Present: Electronic key fob
Later Ascent years also use electronic key fobs, with the exact setup dependent on the model year and trim. We check those details before arranging a replacement or key fob programming.

What to Have Ready for Subaru Ascent Key Replacement
A few vehicle details help identify the right key for your Ascent before service begins. Call first, then have these three things ready:
- The model year and trim — Tell us the Ascent’s year and trim. The key configuration can differ, and these details help narrow down the correct replacement.
- Whether you have a working key — Let us know if one fob still starts the vehicle or if every key is missing. We make a new car key on site when all keys are lost, and that changes what the job involves.
- The vehicle identification number, if available — The VIN can help identify the vehicle’s key configuration. Keep it handy along with the Ascent’s location so we know which vehicle needs service.

One Working Subaru Ascent Key or None: What Changes
Whether you have a working fob affects what is needed to get another key made. Tell us which situation describes your Ascent when you call.
You still have one working key
A working key gives us a reference while arranging a spare. Replacing a lost or damaged Subaru Ascent key fob is easier to plan when you can confirm that the remaining fob still operates the vehicle. Car key replacement starts at $110; Subaru key replacement depends on the exact vehicle configuration.
Every key is gone
Tell us that no original key is available. We can make a new car key on site when all keys are lost; provide the Ascent’s year and trim so the replacement can be matched to the vehicle.
Buying a Used Subaru Ascent With One Key
Getting a spare made before the only fob is lost avoids turning a missing key into an all-keys-lost job. Ask the seller whether the fob starts the Ascent and operates its remote functions, then have the vehicle year and trim ready when you call. A Subaru Ascent key fob replacement starts with matching the key to that specific vehicle; if the fob needs programming, see our key fob programming service. For another Subaru model, we also handle Outback keys.

Frequently asked questions
How long does Subaru Ascent key replacement take at the vehicle?
The time depends on the Ascent’s year, trim, and whether you have a working key. Tell us whether you need a spare or have lost every key so we can account for the job at your vehicle.
Can two drivers share one Subaru Ascent key fob?
Two drivers can share a fob, but only one person can use it at a time. A second programmed fob gives each driver a key to carry, so you are not left relying on a single key.
Will the lost Subaru Ascent key still work after I get a replacement?
A lost fob may still operate the vehicle unless it is removed from the vehicle’s key memory. Tell us that the key is lost and ask whether it can be disabled for your Ascent’s year and trim.
Can you make a Subaru Ascent key if I have no original?
Yes. We make a new car key on site when all keys are lost; share the Ascent’s model year and trim when you call. The exact replacement depends on the vehicle’s configuration.
