FAQ: Suitcase lock trouble Q&A

1. When should you buy a new suitcase?

Title

Suitcases are not something you replace often.
However, in many cases, the "internal fatigue" is more advanced than it appears.

If you leave a problem unattended, it could cause trouble during your trip.

Here we will introduce signs that it's time to replace several parts.

If any of these apply to you, we recommend that you consider this as soon as possible.

1. Abnormal noise and deterioration of caster movement

2. The handle is wobbly and cannot be pulled out

3. Cracks, dents, and broken zippers on the body

4. Malfunction of lock/TSA key

Caster noise and movement deterioration

The most common reason for replacement is "wear and tear of the casters."
If the rubber part is worn down or you hear a rattling noise every time you roll it,
This is a sign that the internal bearings are deteriorating.

If you start to feel resistance from the floor, it's time to consider repairs or replacement.
Especially in winter, the roads are subject to heavy loads due to frozen roads and gravel.
Switching to a model with a well-known caster brand (e.g. New Trip 0502 ) can reduce stress.

Title

The handle is wobbly and cannot be pulled out

The handle is the part that is subjected to the most stress on a daily basis.
If the metal shaft or internal screws become loose, it may cause rattle or
It may get caught in the middle and prevent it from stretching smoothly.

If you experience this symptom, get it checked out as soon as possible.
The cost of repairing a steering wheel is roughly between several thousand yen and 10,000 yen.
If you travel frequently, upgrading to a newer , lighter model will ultimately be cost-effective.

Title

Cracks, dents, and broken zippers on the body

Scratches and dents on the exterior are unavoidable during use,
Cracks or deformations can pose a safety risk.
Suitcases made from poor quality materials lose flexibility over time.
There are many cases where cracks occur due to impact.

If the zipper becomes wavy or the slider becomes easily detached, it is a sign that it is nearing the end of its life.
It is a good idea to replace your luggage early to prevent damage or theft.

Title

Lock/TSA key malfunction

If the TSA lock won't turn or the key won't come out, these kinds of problems are also signs that it's time to buy a new one.
A malfunctioning locking mechanism could cause problems during security checks at airports.
There are cases where the problem can be fixed by replacing parts,

If repair costs are too high, upgrading to a newer model with a TSA lock is a safer and more reliable option.

2. How long does a suitcase last? It depends on the material and how often you use it.

Title

The lifespan of a suitcase cannot be generally stated as "x years."
This varies greatly depending on the type of material used, frequency of use , and storage environment .
By knowing the guidelines, you can prevent sudden damage and trouble, and enjoy your trip with peace of mind.

table of contents

1. Estimated lifespan by material (PC/ABS/fabric, etc.)

2. Lifespan by frequency of use (once a year to once a month)

3. Differences due to storage environment and maintenance conditions

1. Estimated lifespan by material (PC/ABS/fabric, etc.)

The biggest factor that affects the lifespan of a suitcase is the material.
Here we compare the durability of three common materials.

素材タイプ 特徴 寿命の目安
ポリカーボネート（PC） 軽量かつ衝撃に強く、変形しにくい。高品質モデルに多く採用。 約5〜7年
ABS樹脂／PC混合 コスパ重視。やや傷つきやすいが軽く扱いやすい。 約3〜5年
布製（ナイロン・ポリエステル） 軽く柔軟性あり。外装の汚れ・摩耗が早め。 約3〜4年
アルミフレーム 重いが非常に丈夫。ビジネスや長期旅行に◎。 約8〜10年

In recent years, polycarbonate (PC) material has become the mainstream .
" New Trip " suitcases are also made of lightweight PC and ABS + PC mixed materials,
It has an excellent balance of lightness and durability.
Furthermore, if you take proper care of it after use, it can last for over five years.

Title

2. Lifespan by frequency of use (once a year to once a month)

The lifespan of a suitcase also depends on how often you use it.
Even if the material is the same, the strain on the parts will be completely different depending on whether you use it every month or only once a year.

使用頻度 想定シーン 寿命の目安
年1〜2回（旅行・帰省など） レジャー・家族旅行中心 約7〜10年
年3〜5回 出張や国内旅行が多い 約5〜7年
月1回以上（頻繁に出張） ビジネス・空港利用頻度高め 約2〜4年

You might think, "It's okay because I only use it occasionally," but
If stored poorly, deterioration may occur even if the product is not used .
We'll see why in the next section.

Title

3. Differences due to storage environment and maintenance conditions

The biggest factor that shortens the lifespan is the storage environment.
If you leave it in a humid closet or in direct sunlight,
The body may discolor and the metal parts of the casters may rust.

There are three key points to keep in mind when storing:

・Store in a dry, well-ventilated place

After use, dry the inside before storing.

- Cover to protect from dust and UV rays

By simply following these steps, you can extend the life of your suitcase by more than 1.5 times .


Especially the lightweight PC material model like "New Trip"
With proper maintenance, it can stay as shiny as new for a long time.

3. Repair or replace? Decision criteria when you're unsure

Title

When something goes wrong with your suitcase,
Many people probably think, "If I repair it, I can still use it."
However, depending on the repair costs and frequency of part replacement,
In many cases, it ends up being more cost-effective to buy a new one .

Here, we will compare "cases where repair is appropriate" and "cases where it is better to buy a new one,"
Let's take a look at the criteria for making that decision.

1. Cost-effectiveness comparison of repair costs and purchasing a new product

2. Check the warranty period and after-sales service

1. Cost-effectiveness comparison of repair costs and purchasing a new product

The parts that can be repaired are mainly "casters", "handles", "zippers", "locks", etc.
When you add in the cost of parts and labor, the cost can add up surprisingly quickly.

Below are some general repair costs.

修理箇所 費用目安（税込） 判断ポイント
キャスター交換（1〜4輪） 3,000〜8,000円 他の部品も劣化している場合は買い替えを検討
ハンドル修理・交換 4,000〜10,000円 ぐらつきが再発しやすい
ファスナー・スライダー交換 5,000〜9,000円 劣化が全体に広がる前に買い替えがおすすめ
ロック（TSAキー）交換 3,000〜6,000円 空港トラブル防止のため新調が安心
ボディ補修（ヒビ・へこみ） 10,000〜20,000円 費用が高く、買い替え推奨

💡As a general rule of thumb, if the repair cost exceeds 30% of the new price, it's time to buy a new one.
Since other parts often break again after repairs,
If you feel like your furniture is starting to look worn out overall, consider replacing it.

Title

2. Check the warranty period and after-sales service

To ensure you can use your suitcase for a long time, the warranty period and after-sales support system are very important.
Depending on the brand, they offer a free warranty of 1 to 2 years after purchase.
In some cases, they will repair any problems with the casters or locks free of charge.

New Trip has warranty regulations set for each product, and can provide quick part replacement through domestic support.
In particular, models that use HINOMOTO silent casters (e.g., 0502)

It is designed to be highly durable and easy to replace.

In addition, even if the warranty period has expired, repairs can be accepted through official channels,
It's a reliable reference when deciding whether to replace or repair.

💬 修理VS買い替えのまとめ

状況 おすすめの対応
部分的な不具合（1〜2箇所） 修理でOK
全体的に劣化が進行 買い替えを検討
修理費が新品の3割を超える 買い替えがコスパ◎
保証期間内 無償修理を依頼
保証切れ・長期使用後 新モデルへの買い替えがおすすめ

To avoid putting strain on the casters and body, it is best to store it upright .

Ideal storage environment:

  • No direct sunlight
  • Low humidity and well-ventilated place
  • Place a cloth or mat on the area that comes into contact with the floor (to prevent tire marks)

Additionally, cover it with a nonwoven fabric cover during the off-season to prevent dust.

チェック項目 点検ポイント 対応方法
キャスター ゴムの削れ、異音、回転の滑らかさ ゴムの削れ、異音、回転の滑らかさ

FAQ: Suitcase lock trouble Q&A

Title
Q1. スーツケースの平均寿命は何年？

A1. 一般的な目安は5年程度ですが、素材や使用頻度で大きく異なります。高品質なPC（ポリカーボネート）製で年に数回の使用なら7～10年、ABS製や頻繁な使用（出張など）なら2～3年で買い替えが必要になる場合があります。

Q2. キャスター交換だけで延命できますか？

A2. はい、非常に有効な延命策です。キャスターは寿命を左右する重要パーツであり、異音や動きの悪化が出たら、本体に大きな損傷がなければ交換することで快適さが回復し、寿命を大幅に延ばせます。

Q3. 年に1回しか使わない場合も劣化しますか？

A3. はい、使用頻度が少なくても劣化は進みます。特にキャスターなどのゴム・樹脂パーツは、使わなくても日本の高温多湿な環境下で加水分解により劣化します。使用後のクリーニングと湿気を避けた保管が重要です。

Q4. 修理に出すか買い替えるか、どう判断する？

A4. 以下の3点で判断します。 修理費用 vs 新品価格のコスパ： 修理費が新品価格の30%～50%を超える場合は買い替えが合理的です。 その他の劣化の有無： 修理箇所だけでなく、ハンドルやファスナーなど複数の不具合がある場合は、買い替えを推奨します。 保証期間： 保証期間内であれば、まずメーカー保証の適用を確認しましょう。

Q5. 保証期間が切れている場合はどうすべき？

A5. 保証期間外でも、メーカーや専門修理店で有償修理を受け付けています。まずは修理費用の見積もりを取り、新品購入のコストと比較して判断しましょう。

Q6. New Trip製スーツケースの保証内容は？

A6. New Trip製スーツケースは、お買い上げ日から最長2年3ヵ月の保証期間を設けております。この期間内の製造上の欠陥による機能不良は、無償修理または交換で対応いたします。航空会社による破損や不注意による損傷は対象外です。詳細は製品に同梱の保証書をご確認ください。
