There isn't one meaningful price for every new key or faulty door. A car key may need a part, cutting and electronic pairing. A property request may concern an opening, a repair, rekeying or replacement hardware. Those aren't interchangeable jobs.
When you call 201-984-7616, explain what has happened, what still works and where the door or vehicle is. Some details can be discussed before a visit; other faults need assessment of the actual setup.
What changes the scope?
For a vehicle, the year, make, model and whether a working key remains can affect the work. For property locks, the number of cylinders, their condition and compatibility matter. Access arrangements can also change what a visit involves.
Ask whether the estimate includes attendance, the proposed work, parts and the key copies requested. Check for any location-related or time-related charge rather than assuming it is included. The estimate guide gives examples of the questions to compare.
If inspection changes the proposal
Have the cause, the additional work and the price change explained before agreeing. A damaged part may change the assessment, but it should still be clear what the new proposal will address.
At the end, test the functions included in the job and keep an itemized receipt. Ask which warranty terms apply to the actual part and work. This page doesn't publish a fixed price list or a blanket warranty for every request.
Compare the same result
An opening alone isn't the same scope as an opening plus replacement hardware. The service pages help define the task before comparing estimates.
