No. Samsung’s specifications for the Galaxy A03 (model SM-A035) list an accelerometer, light sensor and proximity sensor, but no fingerprint sensor. That means the specified A03 does not support fingerprint unlocking. Samsung’s Galaxy A03 specifications are the basis for this answer.
Galaxy A03 and A03s are different phones
The similar names can cause confusion: Samsung’s specification sheet for the Galaxy A03s explicitly lists a side fingerprint sensor, while its A03 SM-A035 specification list does not. Instructions for setting up fingerprint unlocking on an A03s therefore do not apply to the A03. See Samsung’s Galaxy A03s specification sheet alongside the Galaxy A03 specifications.

Check your exact model before following instructions
Samsung’s regional catalogue labels SM-A035 as Galaxy A03 Core, illustrating that naming can vary by market. That catalogue does not establish that every A03-branded regional variant has identical hardware, so check the complete model name and model number for your own phone rather than relying on “A03” alone. Look on the device box, in the phone’s settings, or on the product listing, then compare that designation with the relevant Samsung specification. The Samsung regional mobile catalogue dated 25 April 2022 is one example of the regional naming difference.
How to unlock a Galaxy A03
Because the cited SM-A035 specification does not list fingerprint hardware, you cannot set up fingerprint unlocking on that model. Use an available screen-lock option in the phone’s settings instead; exact menu wording may vary by software version and region. If you expected a side fingerprint reader, first verify that the phone is an A03s rather than an A03.
