You lost the keys of your Peugeot how can you open it?

smash the window

Get a Slim Jim and shimmy it open. Also most car dealerships have a master key to the cars they sell.

Whoa, all of those suggestions are kinda ridiculous.

Dealers do not have "master keys" - no matter what you've

heard or who you heard it from.

A Slim-Jim... I've been a locksmith for ten years+ - used a Slim-Jim ONCE.

If you don't know exactly what you are doing, chances are you will make your

situation worse.

Smashing the window does not get a you a lost key.

Call a local, reputable locksmith.
