If the automatic locking is the issue, you're fighting the car's system. The slim jim needs to manipulate the locking mechanism *faster* than the car can re-lock. This is extremely difficult.
Here's why it's problematic and what you should consider instead:
* Timing is critical: You need to be incredibly precise and quick with the slim jim to overcome the automatic relocking. Even slight delays will render your efforts futile.
* Damage risk: Forcing the lock with a slim jim can easily bend or break internal components.
* Legal concerns: Unlocking a vehicle that isn't yours is illegal unless you have explicit permission from the owner.
Safer Alternatives:
* Call a locksmith: A professional locksmith has the tools and expertise to unlock your vehicle safely and without causing damage. This is the best and most recommended option.
* Check your spare key: This might sound obvious, but have you really checked everywhere? A spare key hidden away, or a duplicate with a family member, might solve the problem easily.
* AAA or roadside assistance: If you're a member, your roadside assistance plan may include lockout service.
* Contact your dealership: Depending on the situation, they may be able to provide assistance.
While you *can* technically use a slim jim, the potential for damage and the difficulty involved in overcoming the automatic locking make it a highly inadvisable approach. A professional locksmith is always the best solution.
