A mechanical lock that wears out the tumblers due to age or use is acceptable: you use it, it wears, you replace it after x years.
A lock that randomly decides not to work because of unexpected component failure (read: shoddy quality) is unacceptable. What is also unacceptable is the ludicrous price of electronic lock/key replacement, and the reluctance of manufacturers to provide at least one (preferably) two spare keys with the new car, and their apparent inability to provide replacement keys (on their own) at all.
Cars need to have a mechanical-only standby door lock/key, if only to let you into the shelter of the interior in emergencies, whether or not you can then start the engine. If manufacturers move to keyless operation, it will probably take many deaths before they provide a mechanical fallback.
