What to Do Before Booking Service No working Acura key? Separate a lockout from a lost-key job, gather the right vehicle details and arrange access before booking mobile replacement. September 2, 2026Updated October 19, 20264 min readBy Yaroslav Nikulin Quick answer First establish whether the Acura key is locked inside, missing, or present but not working. For a true all-keys-lost job, confirm support for the exact model and year, prepare authorization documents and provide the vehicle location. The 2018 Acura RDX all-keys-lost estimate is $290–$380; confirm the complete quote and availability for your own vehicle. ## Frequently asked questions **What should I do first after losing my Acura key?** Check whether a working key is inside the locked vehicle or available from another authorized driver. If none is available, provide the exact model, year, vehicle location and number of remaining keys when requesting all-keys-lost service. **Can Koala replace an Acura key without the original?** All-keys-lost service is available for supported vehicles. We must confirm the exact model, year, compatible hardware and service availability before booking. A spare-key estimate does not confirm all-keys-lost eligibility. **How much is an all-keys-lost Acura replacement?** For the 2018 Acura RDX, the current all-keys-lost estimate is $290–$380. Select your own model and year at /cars/acura and confirm the complete price, including the agreed service scope, before work begins. **What if my registration is locked inside the Acura?** Tell us before booking. Ask what identification and authorization documents are required and explain where they are. For a rental, company or borrowed vehicle, confirm the authorization arrangement with the responsible owner or organization. **Will replacing the key stop the missing one from working?** Ask what can be disabled electronically on your specific vehicle and whether the missing mechanical blade could still open a lock. Electronic key authorization and the physical lock are separate matters; do not assume that programming a new key changes both. The full guide Complete technical walkthrough & pricing breakdown (4 min read) When the last working Acura key disappears, the first task is to identify the situation correctly. A key inside a locked car needs a different response from a missing key, and a fob in your hand that will not start the engine needs diagnosis. The steps below help you arrange the right service without ordering an incompatible part or transporting the vehicle before support has been checked. For planned spare keys and hardware comparisons, use the [Acura replacement and spare-key guide](https://koala-locksmith.com/blog/2026-09-01-acura-key-replacement-2026-cost-process-tips). ## 1\. Check whether this is actually an all-keys-lost job - **The working key is inside the locked Acura:** Ask about [car lockout service](https://koala-locksmith.com/car-lockout). You may not need a replacement key. - **Another authorized driver has a working key:** Tell the provider whether it can be brought to the vehicle. That may change the service required. - **You have the fob, but the vehicle does not recognize it:** Describe the warning and which functions still work. Use the owner's manual for any documented backup-start procedure and request diagnosis if the problem remains. - **No working key can be located:** Ask specifically for all-keys-lost support for your exact Acura. If the vehicle is in a traffic lane or another unsafe position, address the location risk first. A routine key appointment may not be the appropriate first response to a vehicle blocking traffic. ## 2\. Give the provider enough information to confirm support Have the model year, model, VIN and trim available. Explain whether the car uses a turn-key ignition or push-button start, and whether any damaged or nonworking key remains. A photograph of that key can help identify hardware, but it does not replace checking the actual vehicle. The [Acura catalog](https://koala-locksmith.com/cars/acura) provides model-year selections for [MDX](https://koala-locksmith.com/cars/acura/mdx), [RDX](https://koala-locksmith.com/cars/acura/rdx), [TLX](https://koala-locksmith.com/cars/acura/tlx), [ILX](https://koala-locksmith.com/cars/acura/ilx), [TL](https://koala-locksmith.com/cars/acura/tl) and [TSX](https://koala-locksmith.com/cars/acura/tsx). Select the right year and the all-keys-lost option. Do not choose a spare-key price simply because it is lower. Ask a direct question: "Can you complete an all-keys-lost job on this exact model and year at this location?" Confirm compatible parts and availability before purchasing a blank fob or arranging a tow. ## 3\. Prepare identification and authorization Ask which proof of identity and right to authorize the work will be needed. Have the registration, title or other requested documentation ready. If it is locked in the car, say so before dispatch so the access and verification sequence can be discussed. For a rental, company-owned or borrowed Acura, contact the responsible owner or organization about authorization. Being beside the vehicle does not, by itself, establish permission to commission a new key. ## 4\. Describe access to the car, not just the street address For a driveway, provide the address and any gate instructions. At a workplace or shopping center, include the parking section, nearest entrance and vehicle description. In a garage, give the level and any access restrictions. Tell the provider whether the doors are locked and whether the vehicle has a known battery or ignition problem. Koala serves Jacksonville and the Beaches. Support, current availability and an estimated arrival time are confirmed before dispatch. We do not give every Acura the same completion time because vehicle identification, access and the work required can differ. ## 5\. Approve an all-keys-lost quote for your vehicle For the 2018 Acura RDX, the published all-keys-lost estimate is $290–$380. The [2018 RDX calculator selection](https://koala-locksmith.com/cars/acura/rdx/2018) keeps that example tied to the correct vehicle. It is not a universal Acura price. Confirm the supplied key, applicable blade, programming, vehicle access and mobile visit included in your proposal. Ask about any additional diagnosis or disclosed travel and time-based charges. The complete price should be clear before work begins. If a provider cannot support the vehicle on site, ask the Acura dealer about parts, appointment requirements and whether the car must be transported. Verify those requirements before booking transport. ## 6\. Deal with the missing key and test the replacement If the original key may have been stolen, explain that when requesting service. Ask whether the missing key can be disabled electronically on your particular Acura and what that does to any remaining keys. A mechanical blade and electronic start authorization are separate: disabling one function does not necessarily change the physical door lock. At handover, check the agreed start, remote and blade functions. If you want a second key, request a separate price and confirm that the vehicle supports the proposed service. Do not assume a second key is included in the first quote. Call **+1 (904) 515-9573** or [request an estimate](https://koala-locksmith.com/quote) with the Acura model, year, vehicle location and the fact that no working key remains. If the problem is a key that will not turn, describe it as an [ignition problem](https://koala-locksmith.com/ignition) rather than a lost-key request.
