Picking up a vehicle for car hire in New York should feel straightforward, but keys can be a hidden source of stress. Many rental vehicles are handed over with just one key, and sometimes that key is a valet key with reduced access. That is not automatically wrong, but it changes how you use the car, how you secure luggage, and what you could be charged for if something goes missing or fails.
This guide explains how to confirm you have the correct key or fob, how to test remote locking and boot access before you drive away, and what needs to be noted on the rental agreement so there is no dispute later. It is designed for typical New York pickups, including JFK, Newark, and nearby airport locations.
Why one key or a valet key matters on New York car hire
A single key is common in fleet vehicles because spare keys can get lost between cleans, shuttles, and maintenance. A valet key can also be issued on purpose to reduce risk if a key goes missing. The problem is that the practical differences are easy to miss until you are already on the road, for example when you try to open the boot for luggage at the kerb, pair your phone, or lock valuables in the glovebox.
In New York, you may be juggling tight pickup windows, toll roads, and heavy traffic. If a key function does not work, returning to the counter later can cost time and may lead to fees if the vehicle has to be swapped. Doing a two minute key check in the car park can prevent a much bigger headache.

Step 1: Identify what you have, full key, backup, or valet key
Start by asking a simple question at the desk or booth: “Is this the full-access key and do I have a spare?” Then confirm by looking at what you have been handed.
Full key or full fob typically allows all access: doors, boot, glovebox, and often remote start, if the vehicle has it. It might be a traditional key with buttons, a flip key, or a proximity fob that works with push-button start.
Backup key is often a plain metal key, or a small emergency key blade stored inside a fob. A backup may start the car but not provide remote functions, or may require you to hold the fob close to the start button.
Valet key varies by make, but it is designed to restrict access to certain storage areas. It may open the driver door and start the car, but block glovebox and boot access, or prevent the boot release button from working. Some vehicles can be set to valet mode in the infotainment system, which also limits menus and personal data access.
Watch for clues: a key stamped “VAL” or “VALET”, a fob missing a boot button, or a fob that feels like a basic shell without brand markings. Even if it looks normal, the programming can still be restricted, so you need to test the functions.
Step 2: Test remote locking and unlocking properly
Stand outside the vehicle with all doors closed. You are checking function and range, not just whether the button clicks.
Lock: press lock once. Listen for the locks cycling and watch for hazard light confirmation. Then pull the driver door handle to confirm it is actually locked. On some models, pressing lock twice triggers an audible chirp, if enabled.
Unlock: press unlock once. Confirm the driver door opens. Press unlock twice and check another door to ensure the rest of the car unlocks as expected.
Panic alarm: if your fob has it, press briefly to confirm it activates and can be cancelled. You do not want to discover a sticky button in a hotel car park later.
Remote start: if present, test it once. Some fleets disable it, and some require a specific sequence, for example lock then hold the remote start button. If the car has remote start printed on the fob but it does not work, note it on the agreement so it is not treated as driver error.
Proximity entry: if the car uses keyless entry, lock the car, keep the fob in your pocket, then touch the handle to unlock. Then step away and test whether the door locks via the handle sensor. Weak fob batteries can show up here first.

Step 3: Confirm the boot opens in every normal way
Boot access is the most common surprise with a valet key. Before loading any bags, test all relevant methods so you know what will and will not work during your trip.
Fob boot button: if there is a boot icon, press and hold it as required. Confirm the boot pops and closes properly.
Exterior boot release: many cars have a rubberised button above the number plate or under a trim lip. With the car locked and the fob in your pocket, press it. Some vehicles will not release the boot unless the key is detected. If it does nothing, try with the car unlocked and then locked to understand the behaviour.
Interior boot release: check for a boot button near the driver seat or on the dash. This is important if the exterior release is disabled.
Valet or glovebox lock interaction: on some models, the glovebox has a key slot that can disable the boot release. If it is set to “valet”, the boot may not open from the cabin or the fob. If you cannot change it, that is exactly the kind of limitation to record on the agreement.
Spare tyre and storage access: lift the boot floor briefly. You are not inspecting the whole vehicle here, just checking you can access the area you might need for a puncture kit or to store items. If it is locked or inaccessible, note it.
Step 4: Check whether the key can physically unlock the door
Even with keyless systems, there is usually an emergency key blade hidden inside the fob. Ask where it is and how to remove it. Then locate the manual key slot, which may be behind a small cap on the driver door handle.
This matters because a flat fob battery can leave you locked out. In winter, or after a long day of stop start driving, weak batteries show up. If the manual key is missing, bent, or does not turn smoothly, get it recorded and request a different key or vehicle if necessary.
Step 5: Make sure the car will start, then verify “key not detected” behaviour
Start the vehicle normally. For push-button start, keep the fob where you would naturally store it, such as a pocket or bag, not pressed against the start button. If the car struggles to detect it, the fob battery may be weak.
Then test the backup method: many vehicles allow you to start by holding the fob next to the start button or placing it in a marked pocket in the centre console. Knowing this procedure helps if the battery dies mid-trip.
If you are given a plain metal key and the car has a key slot, turn it fully and confirm it starts without hesitation. Any sticking or warning lights should be flagged immediately.
Step 6: Confirm security limits, glovebox, rear seats, and personal data
Valet restrictions are not only about the boot. Do a quick practical check of any areas where you may store valuables.
Glovebox: open and close it. If it is locked and you cannot unlock it with the provided key, note that you cannot use it for storage.
Rear seat pass-through: if you plan to carry long items, check whether the rear seats fold and whether the release levers are accessible. Some valet modes disable electronic releases.
Infotainment privacy: check whether previous phones are paired or addresses saved. Ask staff to clear profiles if needed. This is not strictly a key issue, but valet mode and restricted keys often go together with fleet privacy settings.
What to have written on the agreement before you leave
If anything is missing, limited, or faulty, get it recorded in writing on the rental agreement or the vehicle condition report. Verbal assurances are easy to forget and hard to prove later.
Ask for these specifics to be documented:
Number of keys provided: “1 key only” or “2 keys provided”.
Key type: “valet key”, “backup key only”, or “full key fob provided”. If it is a valet key, ask them to state “restricted access to boot and glovebox” if that is the case.
Non-working fob functions: list exactly what fails, for example “remote boot release inoperative” or “proximity unlock intermittent”.
Battery condition: if range is weak, note “fob battery low” and request replacement if available. Even if they cannot swap it, the note helps avoid blame.
Instructions provided: if the vehicle requires a special start procedure when the battery is low, have that acknowledged, particularly for push-button start systems.
Any extra charges policy: confirm what happens if the only key is lost. With a single key, loss can be more disruptive because there is no spare to keep the car mobile. Ensure you understand the policy, but keep the focus on accurate documentation.
Take clear photos of the key, both sides, and any markings, plus a short video showing the boot not opening if that is an issue. Keep everything time stamped.
When to insist on a different key or a vehicle swap
Sometimes a note on the agreement is enough, but there are situations where it is safer to resolve it immediately.
Consider requesting a different key or car if:
You cannot access the boot at all and you have luggage, especially for airport pickup.
The car will not reliably detect the fob, showing repeated “key not detected” warnings.
Remote locking fails or works inconsistently, which can become a security issue.
The manual key blade is missing and the vehicle relies on keyless entry.
The key provided does not match the vehicle, which can happen if keys are mixed during cleaning.
If staff can only offer a valet key, ask them to demonstrate that you can open the boot and use the car as you intend. If they cannot, a swap is usually the practical option.
New York specific tips for using a single key safely
New York driving often means frequent stops, paid parking, and tight kerbside loading. With one key, you want habits that reduce the chance of lockouts and lost keys.
Keep the fob on your person rather than in a bag you might leave on the seat.
Do not leave the key in the boot, even briefly. Some cars will still allow the boot to close with the fob inside, particularly if detection is weak.
Check auto-lock settings. Some vehicles lock automatically when you walk away. If your key has limited range, this can lock you out unexpectedly.
Use a consistent routine at toll stops and fuel stations: key in pocket, phone and wallet separate, quick check before closing any door.
For larger groups where access and luggage handling matter, it can help to compare vehicle categories in advance, for example minivan hire New York JFK.
FAQ
Q: Is it normal to receive only one key on car hire in New York?
A: Yes, it is common in rental fleets. The key point is to confirm it works fully and have “one key only” written on the agreement.
Q: How can I tell if I have a valet key rather than a full key?
A: Look for valet markings or missing buttons, then test boot and glovebox access. If either is restricted, ask for it to be recorded as a valet or restricted key.
Q: The fob locks the doors but will not open the boot. What should I do?
A: Test the exterior and interior boot releases too. If boot access is limited or inoperative, get it noted on the paperwork or request another vehicle if you need boot access.
Q: What should be written on the rental agreement about the key?
A: Key count, key type, and any failed functions, such as remote lock range, boot release, or proximity entry. Specific wording helps avoid later disputes.
Q: If I lose the only key, will I be charged?
A: Policies vary, but losing the only key can involve replacement and recovery costs. Reduce risk by keeping the key on you and confirming the manual key blade is present.
