Affordable alternative to overpriced Toyota original key

Since Toyota does not offer "keymats" and RD for the new key. 170 Euro required (with a new transponder)
I came across this alternative:

Ordered key blank, taken keymat and inserted in the original key. - The keys function as on day 1!

Besides, I can leave the grind Locksmiths the blank on occasion, so I one for about 25 euros
have suitable replacement key.

The plastic housing of the transponder is not as stable and high quality as the original key - but I can 6 spare keys
get, instead of Toyota one.

Overall, a top alternative to the original key.
