Hi Jesus. I had the same problem with my P3 where a key required extra pressure to operate. I asked Colin about failure rates and replacements, and he informed me that he had never heard of a key switch malfunctioning, and that they are pretty tough. So I removed the key switch with intent to replace, when i found that one pin was bent under the switch... thus the intermittent contact. I un-bent the pin and it has worked perfectly ever since.
>It's in perfect aesthetic and working condition except for 2 keys (13, 14) which need extra pressure to function.
