OBDStar X300 Pro4 & KeyMaster5 1 Year Update Subscription

The OBDStar X300 Pro4 & KeyMaster5 1 Year Update Subscription is an annual software update license/service for the OBDStar diagnostic and key-programming tools X300 Pro4 and KeyMaster5. It doesn’t include the physical device — it’s specifically the subscription that allows your tool to receive software and database updates for one year.

🛠️ What the Subscription Does

✔️ Software Updates for 12 Months
Once you have this subscription activated, you can update your OBDStar device’s software and car coverage database for the next 12 months. This can include new vehicle support, bug fixes, updated procedures, and enhanced functions.

✔️ Online Activation (No Shipping)
This is a digital service only — after purchase, you must provide your device’s serial number and the update will be activated online (usually within 12–24 hours).
