Can it program keys for any car?

It covers many brands, but support depends on the make, model and year. Check the vehicle list for your car before relying on it for key programming.

Does it read and clear fault codes?

Yes. It reads and clears diagnostic trouble codes, which covers basic engine and system diagnostics. It is not a full dealer-level scan tool for every control module.

Do I need extra keys or blanks?

Usually yes. You need a compatible transponder key or remote for the car, and in some cases a PIN or security access the tool helps retrieve.

How does it compare with a dealer scan tool?

It covers more brands in one device and costs far less, but dealer tools reach deeper into proprietary modules and newer models. For mixed-fleet basic work, the T300 is the more practical choice.

Does it need updates?

Yes. Vehicle coverage and firmware are updated periodically, so plan to keep it current for newer models.

Is it hard to set up?

Setup is straightforward, but key programming procedures differ by brand and take practice. Expect a learning curve before you are confident on customer cars.
