The 2014–2019 Corolla uses the same key setup, so everything on this page applies to those years too. The full picture is on the Toyota Corolla key guide.

Applies to the 2019 Corolla sedan (final E170 year, TOY44H catalog fitment runs 2014-2020). The separate 2019 Corolla hatchback is already the E210 platform with the NXP Hitag-AES 4A smart system — we identify the body style first.

Same key system as the 2014–2019 Corolla

Toyota kept the Corolla's key system unchanged across 2014–2019, so everything about replacing a 2019 key — blanks, programming, and what happens if every key is lost — matches the rest of that run. The full year-by-year breakdown lives in our Toyota Corolla key guide.

What drives the price is the key type, whether you still have a working key, and where the car is parked. There's more on Toyota programming in general on our Toyota key page.
