Nissan Note and Nissan Juke - Ignition key falling apart - Hornblower135

My cousin has a 64 plate Nissan Juke. Both of her ignition keys fell apart. Nissan wanted £200 to replace each key - before eventually doing so under warranty - very reluctantly.

I am considering a Nissan Note Acenta. On test drive yesterday I noted that the ignition key appears to be held together with a tiny cross head screw.

Has anyone else had a problem with Nissan keys. They look VERY flimsy
